Genes affected

ZFYVE1 (HGNC:13180): (zinc finger FYVE-type containing 1) The FYVE domain mediates the recruitment of proteins involved in membrane trafficking and cell signaling to phosphatidylinositol 3-phosphate-containing membranes. This protein contains two zinc-binding FYVE domains in tandem and is reported to localize to the Golgi apparatus. Alternative splicing results in multiple transcript variants.

The c.1868G>A (p.C623Y) alteration is located in exon 10 (coding exon 9) of the ZFYVE1 gene. This alteration results from a G to A substitution at nucleotide position 1868, causing the cysteine (C) at amino acid position 623 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
