Genes affected

ZFYVE27 (HGNC:26559): (zinc finger FYVE-type containing 27) This gene encodes a protein with several transmembrane domains, a Rab11-binding domain and a lipid-binding FYVE finger domain. The encoded protein appears to promote neurite formation. A mutation in this gene has been reported to be associated with hereditary spastic paraplegia, however the pathogenicity of the mutation, which may simply represent a polymorphism, is unclear.

Collection Method:clinical testing

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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with ZFYVE27-related disease. This variant is present in population databases (rs370222554, ExAC 0.002%). This sequence change replaces arginine with glutamine at codon 338 of the ZFYVE27 protein (p.Arg338Gln). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and glutamine.
