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]

Feb 15, 2023

The c.194G>A (p.G65D) alteration is located in exon 2 (coding exon 2) of the ITGBL1 gene. This alteration results from a G to A substitution at nucleotide position 194, causing the glycine (G) at amino acid position 65 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
