Genes affected
ITGA9 (HGNC:6145): (integrin subunit alpha 9) This gene encodes an alpha integrin. Integrins are heterodimeric integral membrane glycoproteins composed of an alpha chain and a beta chain that mediate cell-cell and cell-matrix adhesion. The protein encoded by this gene, when bound to the beta 1 chain, forms an integrin that is a receptor for VCAM1, cytotactin and osteopontin. Expression of this gene has been found to be upregulated in small cell lung cancers. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 01, 2024The c.829G>T (p.V277F) alteration is located in exon 8 (coding exon 8) of the ITGA9 gene. This alteration results from a G to T substitution at nucleotide position 829, causing the valine (V) at amino acid position 277 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
