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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 15, 2024The c.5053C>T (p.R1685C) alteration is located in exon 40 (coding exon 39) of the ITSN2 gene. This alteration results from a C to T substitution at nucleotide position 5053, causing the arginine (R) at amino acid position 1685 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
