Genes affected

CIB3 (HGNC:24580): (calcium and integrin binding family member 3) This gene product shares a high degree of sequence similarity with DNA-dependent protein kinase catalytic subunit-interacting protein 2 in human and mouse, and like them may bind the catalytic subunit of DNA-dependent protein kinases. The exact function of this gene is not known. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

The c.488G>A (p.R163Q) alteration is located in exon 5 (coding exon 5) of the CIB3 gene. This alteration results from a G to A substitution at nucleotide position 488, causing the arginine (R) at amino acid position 163 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
