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]

The c.3085A>G (p.N1029D) alteration is located in exon 25 (coding exon 25) of the ITGA1 gene. This alteration results from a A to G substitution at nucleotide position 3085, causing the asparagine (N) at amino acid position 1029 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
