Genes affected
ITGB1 (HGNC:6153): (integrin subunit beta 1) Integrins are heterodimeric proteins made up of alpha and beta subunits. At least 18 alpha and 8 beta subunits have been described in mammals. Integrin family members are membrane receptors involved in cell adhesion and recognition in a variety of processes including embryogenesis, hemostasis, tissue repair, immune response and metastatic diffusion of tumor cells. This gene encodes a beta subunit. Multiple alternatively spliced transcript variants which encode different protein isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2023The c.2386G>A (p.G796R) alteration is located in exon 15 (coding exon 15) of the ITGB1 gene. This alteration results from a G to A substitution at nucleotide position 2386, causing the glycine (G) at amino acid position 796 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
