Genes affected

PCNX1 (HGNC:19740): (pecanex 1) This gene encodes an evolutionarily conserved transmembrane protein similar to the pecanex protein in Drosophila. The fly protein is a component of the Notch signaling pathway, which functions in several developmental processes. [provided by RefSeq, Jul 2016]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.98).
