Genes affected

ITGB1BP1 (HGNC:23927): (integrin subunit beta 1 binding protein 1) The cytoplasmic domains of integrins are essential for cell adhesion. The protein encoded by this gene binds to the beta1 integrin cytoplasmic domain. The interaction between this protein and beta1 integrin is highly specific. Two isoforms of this protein are derived from alternatively spliced transcripts. The shorter form of this protein does not interact with the beta1 integrin cytoplasmic domain. The longer form is a phosphoprotein and the extent of its phosphorylation is regulated by the cell-matrix interaction, suggesting an important role of this protein during integrin-dependent cell adhesion. Several transcript variants, some protein-coding and some non-protein coding, have been found for this gene. [provided by RefSeq, Jan 2016]

The c.320A>C (p.E107A) alteration is located in exon 5 (coding exon 4) of the ITGB1BP1 gene. This alteration results from a A to C substitution at nucleotide position 320, causing the glutamic acid (E) at amino acid position 107 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
