Variant summary

Our verdict is Uncertain significance. Variant got 5 ACMG points: 6P and 1B. PS1_ModeratePM1PM2BP4

The NM_005192.4(CDKN3):c.273C>G(p.Asn91Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000471 in 1,613,960 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely pathogenic in UniProt.

Genes affected

CDKN3 (HGNC:1791): (cyclin dependent kinase inhibitor 3) The protein encoded by this gene belongs to the dual specificity protein phosphatase family. It was identified as a cyclin-dependent kinase inhibitor, and has been shown to interact with, and dephosphorylate CDK2 kinase, thus prevent the activation of CDK2 kinase. This gene was reported to be deleted, mutated, or overexpressed in several kinds of cancers. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Ambry Genetics

Dec 04, 2024

The c.273C>G (p.N91K) alteration is located in exon 5 (coding exon 5) of the CDKN3 gene. This alteration results from a C to G substitution at nucleotide position 273, causing the asparagine (N) at amino acid position 91 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
