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.2266A>G (p.K756E) alteration is located in exon 14 (coding exon 14) of the ITGB5 gene. This alteration results from a A to G substitution at nucleotide position 2266, causing the lysine (K) at amino acid position 756 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
