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.

Labcorp Genetics (formerly Invitae), Labcorp
Significance: Uncertain significance
Review Status: criteria provided, single submitter
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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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 disruptive. ClinVar contains an entry for this variant (Variation ID: 458217). This variant has not been reported in the literature in individuals affected with ZFYVE27-related conditions. This variant is present in population databases (rs565250413, gnomAD 0.05%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 81 of the ZFYVE27 protein (p.Asn81Ser). -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.242A>G (p.N81S) alteration is located in exon 2 (coding exon 2) of the ZFYVE27 gene. This alteration results from a A to G substitution at nucleotide position 242, causing the asparagine (N) at amino acid position 81 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
