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.1574G>A (p.R525H) alteration is located in exon 10 (coding exon 10) of the ITGB5 gene. This alteration results from a G to A substitution at nucleotide position 1574, causing the arginine (R) at amino acid position 525 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
