Variant 2-117935556-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_019044.5(CCDC93):c.1667G>A(p.Arg556Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000013 in 1,613,738 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. R556W) has been classified as Uncertain significance.

Ambry Genetics

Apr 22, 2022

The c.1667G>A (p.R556Q) alteration is located in exon 22 (coding exon 22) of the CCDC93 gene. This alteration results from a G to A substitution at nucleotide position 1667, causing the arginine (R) at amino acid position 556 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
