Genes affected

ITGB6 (HGNC:6161): (integrin subunit beta 6) This gene encodes a protein that is a member of the integrin superfamily. Members of this family are adhesion receptors that function in signaling from the extracellular matrix to the cell. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. The encoded protein forms a dimer with an alpha v chain and this heterodimer can bind to ligands like fibronectin and transforming growth factor beta 1. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

May 03, 2023

The c.2246G>A (p.R749Q) alteration is located in exon 14 (coding exon 14) of the ITGB6 gene. This alteration results from a G to A substitution at nucleotide position 2246, causing the arginine (R) at amino acid position 749 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
