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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 14, 2023The c.1003T>G (p.F335V) alteration is located in exon 7 (coding exon 7) of the ITGB5 gene. This alteration results from a T to G substitution at nucleotide position 1003, causing the phenylalanine (F) at amino acid position 335 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
