Variant chr2-56184686-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_001080433.2(CCDC85A):c.62C>T(p.Ala21Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000664 in 1,520,774 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 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. A21S) has been classified as Uncertain significance.

The c.62C>T (p.A21V) alteration is located in exon 1 (coding exon 1) of the CCDC85A gene. This alteration results from a C to T substitution at nucleotide position 62, causing the alanine (A) at amino acid position 21 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
