Genes affected

ITSN2 (HGNC:6184): (intersectin 2) This gene encodes a cytoplasmic protein which contains SH3 domains. This protein is a member of a family of proteins involved in clathrin-mediated endocytosis. Intersectin 2 is thought to regulate the formation of clathrin-coated vesicles and also may function in the induction of T cell antigen receptor (TCR) endocytosis. [provided by RefSeq, Jan 2017]

Ambry Genetics

May 06, 2024

The c.4625C>T (p.A1542V) alteration is located in exon 37 (coding exon 36) of the ITSN2 gene. This alteration results from a C to T substitution at nucleotide position 4625, causing the alanine (A) at amino acid position 1542 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
