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]

The c.22G>A (p.D8N) alteration is located in exon 2 (coding exon 1) of the CEMIP gene. This alteration results from a G to A substitution at nucleotide position 22, causing the aspartic acid (D) at amino acid position 8 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
