Genes affected

ITGA1 (HGNC:6134): (integrin subunit alpha 1) This gene encodes the alpha 1 subunit of integrin receptors. This protein heterodimerizes with the beta 1 subunit to form a cell-surface receptor for collagen and laminin. The heterodimeric receptor is involved in cell-cell adhesion and may play a role in inflammation and fibrosis. The alpha 1 subunit contains an inserted (I) von Willebrand factor type I domain which is thought to be involved in collagen binding. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.0982 is higher than 0.05.
