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]

The c.4855A>G (p.N1619D) alteration is located in exon 39 (coding exon 38) of the ITSN2 gene. This alteration results from a A to G substitution at nucleotide position 4855, causing the asparagine (N) at amino acid position 1619 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
