Genes affected

ITGBL1 (HGNC:6164): (integrin subunit beta like 1) This gene encodes a beta integrin-related protein that is a member of the EGF-like protein family. The encoded protein contains integrin-like cysteine-rich repeats. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2012]

The c.686G>A (p.R229Q) alteration is located in exon 5 (coding exon 5) of the ITGBL1 gene. This alteration results from a G to A substitution at nucleotide position 686, causing the arginine (R) at amino acid position 229 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
