Variant chr9-35658677-G-A details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_174923.3(CCDC107):c.208G>A(p.Ala70Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000382 in 1,571,934 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. A70S) has been classified as Uncertain significance.

The c.208G>A (p.A70T) alteration is located in exon 2 (coding exon 2) of the CCDC107 gene. This alteration results from a G to A substitution at nucleotide position 208, causing the alanine (A) at amino acid position 70 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
