The presentation of Ullrich congenital muscular dystrophy in an affected individual is as follows:

- Muscle weakness

- Difficulty walking

- Contractures (neck)

- Joint looseness

Most infants with CMD will display some progressive muscle weakness or muscle wasting (atrophy), although there can be different degrees and symptoms of severeness of progression. The weakness is indicated as "hypotonia", or lack of muscle tone, which can make an infant seem unstable.

Children may be slow with their motor skills; such as rolling over, sitting up or walking, or may not even reach these milestones of life. Some of the more rarer forms of CMD can result in significant learning disabilities.

Congenital muscular dystrophies are autosomal recessively-inherited muscle diseases. They are a group of heterogeneous disorders characterized by muscle weakness which is present at birth and the different changes on muscle biopsy that ranges from myopathic to overtly dystrophic due to the age at which the biopsy takes place.

Ullrich congenital muscular dystrophy is a form of congenital muscular dystrophy.It is associated with variants of type VI collagen, it is commonly associated with muscle weakness and respiratory problems, though cardiac issues are not associated with this type of CMD. It is named after Otto Ullrich, who is also known for the Ullrich-Turner syndrome.

Physical expression of nemaline myopathy varies greatly, but weakness is usually concentrated in the proximal muscles, particularly respiratory, bulbar and trunk muscles. People with severe NM show obvious symptoms at birth, while those with intermediate or mild NM may initially appear unaffected. Babies with NM are frequently observed to be "floppy" and hypotonic. Children born with NM often gain strength as they grow, though the effect of muscle weakness on body features may become more evident with time. Adults with NM typically have a very slender physique.

Bulbar (throat) muscle weakness is a main feature of nemaline myopathy. Most individuals with severe NM are unable to swallow and receive their nutrition through feeding tubes. Most people with intermediate and mild NM take some or all of their nutrition orally. Bulbar muscle impairment may also lead to difficulty with communication. People with NM often have hypernasal speech as a result of poor closure of the velopharyngeal port (between the soft palate and the back of the throat). Communicative skills may be enhanced through speech therapy, oral prosthetic devices, surgery, and augmentative communication devices. Individuals with NM are usually highly sociable and intelligent, with a great desire to communicate.

Familial partial lipodystrophy (FPL), also known as Köbberling–Dunnigan syndrome, is a rare genetic metabolic condition characterized by the loss of subcutaneous fat.

FPL also refers to a rare metabolic condition in which there is a loss of subcutaneous fat in the arms, legs and lower torso. The upper section of the body, face, neck, shoulders, back and trunk carry an excess amount of fat.

As the body is unable to store fat correctly this leads to fat around all the vital organs and in the blood (triglycerides). This results in heart problems, cirrhosis of the liver, lipoatrophic diabetes, and pancreatitis, along with various other complications.

Campomelic dysplasia (CMD) is a rare genetic disorder characterized by bowing of the long bones and many other skeletal and extraskeletal features.

It is frequently lethal in the neonatal period due to respiratory insufficiency, but the severity of the disease is variable, and some patients survive into adulthood.

The name is derived from the Greek roots "campo" (or "campto"), meaning bent, and "melia", meaning limb.

An unusual aspect of the disease is that up to two-thirds of affected 46,XY genotypic males display a range of Disorders of Sexual Development (DSD) and genital ambiguities or may even develop as normal phenotypic females as in complete 46 XY sex reversal.

An atypical form of the disease with absence of bowed limbs is called, prosaically, acampomelic campomelic dysplasia (ACD) and is found in about 10% of patients, particularly those surviving the neonatal period.

While the definitive presentation of the disease is a patient having bowed lower limbs and sex reversal in 46,XY males, there are other clinical criteria that can be used, absent these characteristics, to make the diagnosis. Patients may present with underdeveloped shoulder blades, shortened and angulated lower limbs, a vertically oriented and narrow pelvis, an enlarged head, an undersized jaw, cleft palate, flat nasal bridge, low set ears, club feet, dislocated hips, 11 pairs of ribs instead of 12, or bone abnormalities in the neck and spine. Respiratory distress can be caused by an underdeveloped trachea which collapses on inhalation or by insufficient rib cage development.

A mutations in a number of genes have been associated with this condition. Mutations associated with FPL have been reported in "LMNA" (lamin A/C), "PPARG" (PPARγ), "AKT2" (AKT serine/threonine kinase 2), "PLIN1" (perilipin-1), and "CIDEC" (cell-death-inducing DFFA-like effector B).

Six types (1-6) have been described. Types 1-5 are inherited in an autosomal dominant fashion.

Type 1 (Kobberling variety, FPL1) is very rare and has only been reported in women to date. Fat loss is confined to the limbs and mostly in the distal parts. Central obesity may be present. Complications include hypertension, insulin resistance and hypertriglyceridemia. The gene causing this condition is not yet known. This form was first described in 1975.

Type 2 (Dunnigan Variety, FPL2) is the most common form and is due to mutations in the LMNA gene. Over 500 cases have been reported to date. Development up to puberty is normal. Fat is then gradually lost in is the limbs and trunk. Fat may accumulate around the face and between the shoulder blades. Insulin resistance is common. Other conditions associated with this condition include acanthosis nigricans, fatty liver, hypertriglyceridemia and polycystic ovary syndrome in women. There is an increased risk of coronary heart disease. Cardiomyopathy and muscular dystrophy may occur rarely. Xanthoma and nail changes may occur.

Type 3 is due to mutations in the PPARG gene. It is rare with approximately 30 cases reported to date. It is similar to type 2 but tends to be milder.

Type 4 is due to mutations in the PLIN1 gene. It is rare with only a small number of cases reported. Fat loss tends to affect the lower limbs and buttocks. Insulin resistance and hypertriglyceridemia occur. Calf muscular hypertrophy may occur.

Type 5 is due to mutations in the AKT2 gene. It has been reported in four patients all members of the same family. Fat loss affects the upper and lower limbs. The patients also suffered from hypertension, insulin resistance and hypertriglyceridemia.

Type 6 due to mutations in the CIDEC gene. It is inherited in an autosomal recessive fashion and has been reported in only one patient to date. Features included fat loss, severe insulin resistance, fatty liver, acanthosis nigricans and diabetes.

Dubin–Johnson syndrome (DJS) is a rare, autosomal recessive, benign disorder that causes an isolated increase of conjugated bilirubin in the serum. Classically, the condition causes a black liver due to the deposition of a pigment similar to melanin. This condition is associated with a defect in the ability of hepatocytes to secrete conjugated bilirubin into the bile, and is similar to Rotor syndrome. It is usually asymptomatic, but may be diagnosed in early infancy based on laboratory tests. No treatment is usually needed.

Signs and symptoms of temporomandibular joint disorder vary in their presentation. The symptoms will usually involve more than one of the various components of the masticatory system, muscles, nerves, tendons, ligaments, bones, connective tissue, or the teeth.

The three classically described, cardinal signs and symptoms of TMD are:

- Pain and tenderness on palpation in the muscles of mastication, or of the joint itself (preauricular pain – pain felt just in front of the ear). Pain is the defining feature of TMD and is usually aggravated by manipulation or function, such as when chewing, clenching, or yawning, and is often worse upon waking. The character of the pain is usually dull or aching, poorly localized, and intermittent, although it can sometimes be constant. The pain is more usually unilateral (located on one side) rather than bilateral. It is rarely severe.

- Limited range of mandibular movement, which may cause difficulty eating or even talking. There may be locking of the jaw, or stiffness in the jaw muscles and the joints, especially present upon waking. There may also be incoordination, asymmetry or deviation of mandibular movement.

- Noises from the joint during mandibular movement, which may be intermittent. Joint noises may be described as clicking, popping, or crepitus (grating).

Other signs and symptoms have also been described, although these are less common and less significant than the cardinal signs and symptoms listed above. Examples include:

- Headache (possibly), e.g. pain in the occipital region (the back of the head), or the forehead; or other types of facial pain including migraine, tension headache. or myofascial pain.

- Pain elsewhere, such as the teeth or neck.

- Diminished auditory acuity (hearing loss).

- Tinnitus (occasionally).

- Dizziness.

- Sensation of malocclusion (feeling that the teeth do not meet together properly).

Sometimes distinction is made between acute TMD, where symptoms last for less than 3 months, and chronic TMD, where symptoms last for more than 3 months. Not much is known about acute TMD since these individuals do not typically attend in secondary care (hospital).

Dubin–Johnson syndrome is similar to Rotor syndrome, but can be differentiated by:

Most affected cats present with muscular weakness and/or ocular signs of hypertension. Signs of muscle weakness can include a plantigrade stance of the hindlimbs, cervical ventroflexion, inability to jump, lateral recumbency, or collapse. Ocular signs of arterial hypertension include mydriasis, hyphema, or blindness due to retinal detachment and/or intraocular hemorrhages. A palpable mass in the cranial abdomen is another potential finding.

Trifascicular block is a problem with the electrical conduction of the heart. It is diagnosed on an electrocardiogram (ECG/EKG) and has three features:

- prolongation of the (first degree AV block)

- right bundle branch block

- either left anterior fascicular block or left posterior fascicular block.

Bernard–Soulier syndrome often presents as a bleeding disorder with symptoms of:

Trifascicular block is important to diagnose because it is difficult to tell based on the surface ECG whether the prolonged PR interval is due to disease in the AV node or due to diffuse distal conduction system disease.

- In the former case, if the block at the AV node level becomes complete, the escape rhythm will originate from the bundle of His, which typically will generate heart rates in the 40s, allowing the individual to survive and complain of symptoms of fatigue or near-syncope to their physician.

- In the latter case, however, because the conduction system disease is diffuse in nature, the escape rhythm may be fascicular or ventricular, which may be at rates that are life-threateningly low.

Typically an attack occurs without warning leading to sudden loss of consciousness. Prior to an attack, a patient may be pale with hypoperfusion. Normal periods of unconsciousness last approximately thirty seconds; if abnormal movements are present, they will consist of twitching after 15–20 seconds (The movements, which are not seizures occur because of brainstem hypoxia and not due to cortical discharge as evident by EEG findings which show no epileptiform activities). Breathing continues normally throughout the attack, and upon recovery the patient becomes flushed as the heart rapidly pumps the oxygenated blood from the pulmonary beds into a systemic circulation, which has become dilated due to hypoxia.

As with any syncopal episode that results from a cardiac dysrhythmia, the faints do not depend on the patient's position. If they occur during sleep, the presenting symptom may simply be feeling hot and flushed on waking.

Stokes-Adams attacks may be diagnosed from the history, with paleness prior to the attack and flushing after it particularly characteristic. The ECG will show asystole, an AV block, or ventricular fibrillation during the attacks.

Hyperlysinuria is marked by high amounts of the amino acid lysine in the urine. It is often due to a metabolic disease in which a protein involved in the breakdown of lysine is non functional due to a genetic mutation. It may also occur due to a failure of renal tubular transport.

Congenital hypogonadotropic hypogonadism presents as hypogonadism, e.g., reduced or absent puberty, low libido, infertility, etc. due to an impaired release of the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and a resultant lack of sex steroid and peptides production by the gonads.

In Kallmann syndrome, a variable non-reproductive phenotype occurs with anosmia (loss of the sense of smell) including sensorineural deafness, coloboma, bimanual synkinesis, craniofacial abnormalities, and/or renal agenesis.

It can present with the following:

- severe burning pain

- lacrimation

- photophobia

- blepharospasm

- swelling of palpebral conjunctiva

- retrotarsal folds

Sarcopenic obesity is a medical condition which is defined as the presence of both sarcopenia and obesity. Sarcopenia refers to the presence of low muscle mass and either low muscular strength or low physical performance. When this is accompanied by a high fat mass the condition is known as sarcopenic obesity.

The symptoms are basically the same as that of sarcopenia and obesity. The individual may show a BMI that is appropriate and healthy to his or her age but will look fat in appearance.
