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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

Collection Method: clinical testing

The c.410G>A (p.R137Q) 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 410, causing the arginine (R) at amino acid position 137 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
