Genes affected

CCNI (HGNC:1595): (cyclin I) The protein encoded by this gene belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. This cyclin shows the highest similarity with cyclin G. The transcript of this gene was found to be expressed constantly during cell cycle progression. [provided by RefSeq, Jan 2017]

The c.950A>G (p.K317R) alteration is located in exon 7 (coding exon 6) of the CCNI gene. This alteration results from a A to G substitution at nucleotide position 950, causing the lysine (K) at amino acid position 317 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
