Genes affected

CEMIP (HGNC:29213): (cell migration inducing hyaluronidase 1) Enables several functions, including clathrin heavy chain binding activity; hyaluronic acid binding activity; and hyalurononglucosaminidase activity. Involved in several processes, including hyaluronan catabolic process; positive regulation of protein phosphorylation; and positive regulation of transport. Located in clathrin-coated endocytic vesicle; endoplasmic reticulum; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.198 is higher than 0.05.
