Genes affected

VPS37A (HGNC:24928): (VPS37A subunit of ESCRT-I) This gene belongs to the VPS37 family, and encodes a component of the ESCRT-I (endosomal sorting complex required for transport I) protein complex, required for the sorting of ubiquitinated transmembrane proteins into internal vesicles of multivesicular bodies. Expression of this gene is downregulated in hepatocellular carcinoma, and mutations in this gene are associated with autosomal recessive spastic paraplegia-53. A related pseudogene has been identified on chromosome 5. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2012]

The c.787A>C (p.K263Q) alteration is located in exon 7 (coding exon 7) of the VPS37A gene. This alteration results from a A to C substitution at nucleotide position 787, causing the lysine (K) at amino acid position 263 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt VPS37A protein function. ClinVar contains an entry for this variant (Variation ID: 569194). This variant has not been reported in the literature in individuals affected with VPS37A-related conditions. This variant is present in population databases (rs199781923, gnomAD 0.006%). This sequence change replaces lysine, which is basic and polar, with glutamine, which is neutral and polar, at codon 263 of the VPS37A protein (p.Lys263Gln). -
