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

Oct 27, 2023

The c.388A>G (p.T130A) alteration is located in exon 3 (coding exon 3) of the ITGBL1 gene. This alteration results from a A to G substitution at nucleotide position 388, causing the threonine (T) at amino acid position 130 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
