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]

The c.2185A>T (p.I729F) alteration is located in exon 14 (coding exon 14) of the ITGB1 gene. This alteration results from a A to T substitution at nucleotide position 2185, causing the isoleucine (I) at amino acid position 729 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
