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.445A>T (p.I149F) alteration is located in exon 3 (coding exon 3) of the ITGBL1 gene. This alteration results from a A to T substitution at nucleotide position 445, causing the isoleucine (I) at amino acid position 149 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
