Genes affected

ITGA11 (HGNC:6136): (integrin subunit alpha 11) This gene encodes an alpha integrin. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This protein contains an I domain, is expressed in muscle tissue, dimerizes with beta 1 integrin in vitro, and appears to bind collagen in this form. Therefore, the protein may be involved in attaching muscle tissue to the extracellular matrix. Alternative transcriptional splice variants have been found for this gene, but their biological validity is not determined. [provided by RefSeq, Jul 2008]

The c.3046G>A (p.G1016S) alteration is located in exon 25 (coding exon 25) of the ITGA11 gene. This alteration results from a G to A substitution at nucleotide position 3046, causing the glycine (G) at amino acid position 1016 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
