Genes affected

SYNJ1 (HGNC:11503): (synaptojanin 1) This gene encodes a phosphoinositide phosphatase that regulates levels of membrane phosphatidylinositol-4,5-bisphosphate. As such, expression of this enzyme may affect synaptic transmission and membrane trafficking. Multiple transcript variants encoding different isoforms have been found for this gene.

This variant is present in population databases (rs547450707, gnomAD 0.03%). This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 309 of the SYNJ1 protein (p.Arg309Cys). This variant has not been reported in the literature in individuals affected with SYNJ1-related conditions. ClinVar contains an entry for this variant (Variation ID: 478367). 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. 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. -
