Genes affected

ITGB3BP (HGNC:6157): (integrin subunit beta 3 binding protein) This gene encodes a transcriptional coregulator that binds to and enhances the activity of members of the nuclear receptor families, thyroid hormone receptors and retinoid X receptors. This protein also acts as a corepressor of NF-kappaB-dependent signaling. This protein induces apoptosis in breast cancer cells through a caspase 2-mediated signaling pathway. This protein is also a component of the centromere-specific histone H3 variant nucleosome associated complex (CENP-NAC) and may be involved in mitotic progression by recruiting the histone H3 variant CENP-A to the centromere. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2011]

The c.445A>G (p.I149V) alteration is located in exon 6 (coding exon 6) of the ITGB3BP gene. This alteration results from a A to G substitution at nucleotide position 445, causing the isoleucine (I) at amino acid position 149 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
