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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2022The c.757G>A (p.A253T) alteration is located in exon 7 (coding exon 7) of the ITGA9 gene. This alteration results from a G to A substitution at nucleotide position 757, causing the alanine (A) at amino acid position 253 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
