Genes affected

MADCAM1 (HGNC:6765): (mucosal vascular addressin cell adhesion molecule 1) The protein encoded by this gene is an endothelial cell adhesion molecule that interacts preferentially with the leukocyte beta7 integrin LPAM-1 (alpha4beta7), L-selectin, and VLA-4 (alpha4beta1) on myeloid cells to direct leukocytes into mucosal and inflamed tissues. It is a member of the immunoglobulin family and is similar to ICAM1 and VCAM1. At least seven alternatively spliced transcripts encoding different protein isoforms have been found for this gene, but the full-length nature of some variants has not been determined.

The c.29C>T (p.A10V) alteration is located in exon 1 (coding exon 1) of the MADCAM1 gene. This alteration results from a C to T substitution at nucleotide position 29, causing the alanine (A) at amino acid position 10 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
