Variant 5-132747802-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001039780.4(CCNI2):c.307C>T(p.Pro103Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000473 in 1,478,474 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P103R) has been classified as Uncertain significance.

Ambry Genetics

Dec 11, 2023

The c.307C>T (p.P103S) alteration is located in exon 1 (coding exon 1) of the CCNI2 gene. This alteration results from a C to T substitution at nucleotide position 307, causing the proline (P) at amino acid position 103 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
