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.3249T>A (p.D1083E) alteration is located in exon 29 (coding exon 29) of the ITGAE gene. This alteration results from a T to A substitution at nucleotide position 3249, causing the aspartic acid (D) at amino acid position 1083 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
