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]
ITGA2-AS1 (HGNC:40306): (ITGA2 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 19, 2023The c.3186C>G (p.C1062W) alteration is located in exon 26 (coding exon 26) of the ITGA1 gene. This alteration results from a C to G substitution at nucleotide position 3186, causing the cysteine (C) at amino acid position 1062 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
