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]

The c.395C>T (p.A132V) alteration is located in exon 1 (coding exon 1) of the PRPH gene. This alteration results from a C to T substitution at nucleotide position 395, causing the alanine (A) at amino acid position 132 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
