Genes affected

ZFYVE16 (HGNC:20756): (zinc finger FYVE-type containing 16) This gene encodes an endosomal protein that belongs to the FYVE zinc finger family of proteins. The encoded protein is thought to regulate membrane trafficking in the endosome. This protein functions as a scaffold protein in the transforming growth factor-beta signaling pathway and is involved in positive and negative feedback regulation of the bone morphogenetic protein signaling pathway. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

The c.539A>G (p.H180R) alteration is located in exon 4 (coding exon 2) of the ZFYVE16 gene. This alteration results from a A to G substitution at nucleotide position 539, causing the histidine (H) at amino acid position 180 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
