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]

FAM151B-DT (HGNC:55578): (FAM151B divergent transcript)

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.07192138).

The c.502T>C (p.S168P) alteration is located in exon 4 (coding exon 2) of the ZFYVE16 gene. This alteration results from a T to C substitution at nucleotide position 502, causing the serine (S) at amino acid position 168 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
