Genes affected

ITGAE (HGNC:6147): (integrin subunit alpha E) Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This gene encodes an I-domain-containing alpha integrin that undergoes post-translational cleavage in the extracellular domain, yielding disulfide-linked heavy and light chains. In combination with the beta 7 integrin, this protein forms the E-cadherin binding integrin known as the human mucosal lymphocyte-1 antigen. This protein is preferentially expressed in human intestinal intraepithelial lymphocytes (IEL), and in addition to a role in adhesion, it may serve as an accessory molecule for IEL activation.

The c.3170G>A (p.C1057Y) alteration is located in exon 28 (coding exon 28) of the ITGAE gene. This alteration results from a G to A substitution at nucleotide position 3170, causing the cysteine (C) at amino acid position 1057 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
