Genes affected
WASHC5 (HGNC:28984): (WASH complex subunit 5) This gene encodes a 134 kDa protein named strumpellin that is predicted to have multiple transmembrane domains and a spectrin-repeat-containing domain. This ubiquitously expressed gene has its highest expression in skeletal muscle. The protein is named for Strumpell disease; a form of hereditary spastic paraplegia (HSP). Spastic paraplegias are a diverse group of disorders in which the autosomal dominant forms are characterized by progressive, lower extremity spasticity caused by axonal degeneration in the terminal portions of the longest descending and ascending corticospinal tracts. More than 30 loci (SPG1-33) have been implicated in hereditary spastic paraplegia diseases. [provided by RefSeq, Aug 2009]

Hereditary spastic paraplegia 8;C4551776:Ritscher-Schinzel syndrome 1 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeOct 12, 2017This sequence change replaces serine with asparagine at codon 291 of the WASHC5 protein (p.Ser291Asn). The serine residue is moderately conserved and there is a small physicochemical difference between serine and asparagine. This variant is present in population databases (rs753529606, ExAC 0.01%). This variant has not been reported in the literature in individuals with WASHC5-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
