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]

Ritscher-Schinzel syndrome;C1863704:Hereditary spastic paraplegia 8 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 17, 2015This sequence change replaces isoleucine with threonine at codon 54 of the KIAA0196 protein (p.Ile54Thr). The isoleucine residue is moderately conserved and there is a moderate physicochemical difference between isoleucine and threonine. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "possibly damaging"; Align-GVGD: "Class C0"). In summary, this is a rare missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. This variant has not been published in the literature and is present in population databases (rs199936194, 0.05%). -
