Genes affected

ZFYVE26 (HGNC:20761): (zinc finger FYVE-type containing 26) This gene encodes a protein which contains a FYVE zinc finger binding domain. The presence of this domain is thought to target these proteins to membrane lipids through interaction with phospholipids in the membrane. Mutations in this gene are associated with autosomal recessive spastic paraplegia-15. [provided by RefSeq, Oct 2008]

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 318 of the ZFYVE26 protein (p.Glu318Lys). This variant is present in population databases (rs758568084, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with ZFYVE26-related conditions. ClinVar contains an entry for this variant (Variation ID: 528008). 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. 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. -
