Genes affected
PRPH (HGNC:9461): (peripherin) This gene encodes a cytoskeletal protein found in neurons of the peripheral nervous system. The encoded protein is a type III intermediate filament protein with homology to other cytoskeletal proteins such as desmin, and is a different protein that the peripherin found in photoreceptors. Mutations in this gene have been associated with susceptibility to amyotrophic lateral sclerosis. [provided by RefSeq, Jul 2008]
TROAP-AS1 (HGNC:55453): (TROAP and PRPH antisense RNA 1)

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 06, 2023The c.104C>G (p.S35W) alteration is located in exon 1 (coding exon 1) of the PRPH gene. This alteration results from a C to G substitution at nucleotide position 104, causing the serine (S) at amino acid position 35 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
