Name

SMAR Gene

Spinal muscular atrophy, chronic distal, autosomal recessive

SMAL Gene

spinal muscular atrophy, congenital nonprogressive, of lower limbs

SMAJ Gene

Spinal muscular atrophy, Jokela type

SCA18 Gene

spinocerebellar ataxia 18 (sensory with neurogenic muscular atrophy)

RRIS Gene

Respiratory rhythmicity in sleep

NRF1 Gene

nuclear respiratory factor 1

This gene encodes a protein that homodimerizes and functions as a transcription factor which activates the expression of some key metabolic genes regulating cellular growth and nuclear genes required for respiration, heme biosynthesis, and mitochondrial DNA transcription and replication. The protein has also been associated with the regulation of neurite outgrowth. Alternative splicing results in multiple transcript variants. Confusion has occurred in bibliographic databases due to the shared symbol of NRF1 for this gene and for `nuclear factor (erythroid-derived 2)-like 1` which has an official symbol of NFE2L1.

MDRV Gene

muscular dystrophy, with rimmed vacuoles

MLIP Gene

muscular LMNA-interacting protein

Predicted to enable lamin binding activity and transcription corepressor activity. Predicted to be involved in negative regulation of cardiac muscle hypertrophy in response to stress; negative regulation of transcription by RNA polymerase II; and positive regulation of transcription by RNA polymerase II. Predicted to be located in PML body; nuclear envelope; and sarcolemma. [provided by Alliance of Genome Resources, Mar 2025]

LGMD1H Gene

limb girdle muscular dystrophy 1H (autosomal dominant)

LGMD1G Gene

limb girdle muscular dystrophy 1G (autosomal dominant)

MDC1B Gene

Muscular dystrophy, congenital, 1B

FSHMD1A Gene

facioscapulohumeral muscular dystrophy 1A

Facioscapulohumeral muscular dystrophy (FSHD) is a common hereditary disease of muscle. Patients with FSHD have a chromosomal rearrangement within the subtelomeric region of chromosome 4 (4q35). This region is composed mainly of a polymorphic repeat structure consisting of 3.3 kb repeat units, designated D4Z4. The number of repeat units varies from 10 to more than 100 in the population, however, in FSHD patients only 1-10 repeat units is observed because of a deletion of an integral number of these units. FSHD is caused by an epigenetic mechanism involving the contraction of a subtelomeric macrosatellite repeat, which results in marked hypomethylation of the contracted D4Z4 allele. It is likely not the structure, but the deregulation of transcription of one or more genes as a result of repeat-contraction-mediated chromatin alterations, that causes FSHD.

FSHMD1B Gene

facioscapulohumeral muscular dystrophy 1B

MDCMP Gene

muscular dystrophy, congenital, merosin-positive

OPA6 Gene

optic atrophy 6 (autosomal recessive)

OPA4 Gene

optic atrophy 4 (autosomal dominant)

OPA5 Gene

optic atrophy 5 (autosomal dominant)

OPA2 Gene

optic atrophy 2 (obscure)

OPA1 Gene

optic atrophy 1 (autosomal dominant)

The protein encoded by this gene is a nuclear-encoded mitochondrial protein with similarity to dynamin-related GTPases. The encoded protein localizes to the inner mitochondrial membrane and helps regulate mitochondrial stability and energy output. This protein also sequesters cytochrome c. Mutations in this gene have been associated with optic atrophy type 1, which is a dominantly inherited optic neuropathy resulting in progressive loss of visual acuity, leading in many cases to legal blindness.

OPA3 Gene

optic atrophy 3 (autosomal recessive, with chorea and spastic paraplegia)

The mouse ortholog of this protein co-purifies with the mitochondrial inner membrane. Mutations in this gene have been shown to result in 3-methylglutaconic aciduria type III and autosomal dominant optic atrophy and cataract. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009]

PBCRA1 Gene

progressive bifocal chorioretinal atrophy 1

SPOAN Gene

spastic paraplegia, optic atrophy, and neuropathy

CLAM Gene

cerebellar atrophy with progressive microcephaly

LOAS Gene

Leber optic atrophy, susceptibility to
