Prepair 1000+ v1.633 IMPG2 Andrew Coventry changed review comment from: Retinitis pigmentosa 56 - is an early-onset form of RP with progressive visual-field loss and deterioration of visual acuity. Features include night blindness, progressive visual loss, macular retinal pigment epithelium (RPE) mottling / atrophy, decreased ERG amplitudes (affecting rods more severely than cones), colour vision defect, peripheral visual field loss, central scotoma, retinal blood vessel attenuation, and/or optic disc pallor. These features are largely distinct from the vitelliform macular dystrophy phenotype (MIM#616152).
- biallelic loss-of-function consistently associates with retinitis pigmentosa, while monoallelic loss-of-function consistently associates with vitelliform macular dystrophy.
PMID: 20673862 - 2 families each with 3 affected sibs. Additional 10 index cases identified.
- Those with nonsenses showed early-onset RP, patient with missense variants had a milder maculopathy phenotype.

Further studies and evidence:
Mouse models present exhibiting RP phenotype. (PMID: 38217426 - indicates missense variants had minimal retinal pathology in mice)
Functional study present using patient derived iPS (PMID: 36206764) - confirmed LoF due to lack of expression or lack os post-translational modifications - destabilising outer segments of rods and cones.

Charcot-Marie-Tooth disease type 2X (CMT2X) is an autosomal recessive, slowly progressive, axonal peripheral sensorimotor neuropathy characterized by lower limb muscle weakness and atrophy associated with distal sensory impairment and gait difficulties. Some patients also have involvement of the upper limbs. Onset usually occurs in the first 2 decades of life, although later onset can also occur (summary by Montecchiani et al., 2016). Mean age of onset 11.4 years.

Hereditary spastic paraplegia (SPG or HSP) is characterized by progressive weakness and spasticity of the lower limbs due to degeneration of corticospinal axons. SPG11 is a form of complicated SPG, in that it has neurologic features in addition to spasticity.

Autosomal recessive limb-girdle muscular dystrophy type 2B (LGMD2B) is a subtype of autosomal recessive limb-girdle muscular dystrophy characterized by an onset in late adolescence or early adulthood of slowly progressive, proximal weakness and atrophy of shoulder and pelvic girdle muscles. Cardiac and respiratory muscles are not involved. Hypertrophy of the calf muscles and highly elevated serum creatine kinase levels are frequently observed.

Myopathy, distal, with anterior tibial onset is a rare genetic neuromuscular disease with characteristics of a progressive muscle weakness starting in the anterior tibial muscles, later involving lower and upper limb muscles, associated with an increased serum creatine kinase levels and absence of dysferlin on muscle biopsy. Patients become wheelchair dependent.

Prepair 1000+ v1.5 ADPRHL2 Zornitza Stark changed review comment from: Fourteen unrelated families reported with stress-induced childhood-onset neurodegeneration with variable ataxia and seizures (CONDSIAS), an autosomal recessive neurodegenerative disorder with onset in the first years of life following normal early development. The disorder is characterised by cyclic episodic deterioration in response to stress, such as infection or febrile illness. The severity is highly variable: some individuals develop seizures early in life that are associated with loss of developmental milestones and early sudden death in childhood, whereas others present at a later age with muscle weakness, gait ataxia, impaired speech, more subtle clinical deterioration, and cognitive decline. Neurologic involvement includes gait ataxia, cerebellar signs associated with cerebellar atrophy, generalized brain atrophy, impaired intellectual development, hearing loss, and peripheral neuropathy.

Review for gene: PYGM was set to AMBER
Added comment: Gene-disease association for bi-allelic variants is well established.

McCardle disease: glycogen storage disease type V (GSD5), characterized by onset of exercise intolerance and muscle cramps in childhood or adolescence. Transient myoglobinuria may occur after exercise, due to rhabdomyolysis. Severe myoglobinuria may lead to acute renal failure. Patients may report muscle weakness, myalgia, and lack of endurance since childhood or adolescence. Later in adult life, there is persistent and progressive muscle weakness and atrophy with fatty replacement. McArdle disease is a relatively benign disorder, except for possible renal failure as a complication of myoglobinuria

Clinical heterogeneity exists; about 10% of all affected individuals have mild manifestations (e.g., fatigue or poor stamina without contractures) and remain virtually asymptomatic during daily activities of living(Gene Reviews)

Added comment: Biallelic variants associated with deficiency of mitochondrial enzyme ornithine aminotransferase and elevation of plasma ornithine levels without elevation of ammonia. Characterized by ocular anomalies; however, neurological and muscular features may also be present.

There is evidence of intra-familial variability.
