Genes affected

ITGB5 (HGNC:6160): (integrin subunit beta 5) This gene encodes a beta subunit of integrin, which can combine with different alpha chains to form a variety of integrin heterodimers. Integrins are integral cell-surface receptors that participate in cell adhesion as well as cell-surface mediated signaling. The alphav beta5 integrin is involved in adhesion to vitronectin.

The c.2122G>A (p.V708I) alteration is located in exon 13 (coding exon 13) of the ITGB5 gene. This alteration results from a G to A substitution at nucleotide position 2122, causing the valine (V) at amino acid position 708 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
