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]

Ambry Genetics

Feb 28, 2023

The c.197G>T (p.R66L) alteration is located in exon 2 (coding exon 2) of the ITGBL1 gene. This alteration results from a G to T substitution at nucleotide position 197, causing the arginine (R) at amino acid position 66 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
