Variant 12-110019267-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_033121.2(ANKRD13A):c.673C>T(p.Arg225Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000166 in 1,613,966 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. R225Q) has been classified as Uncertain significance.

The c.673C>T (p.R225W) alteration is located in exon 6 (coding exon 6) of the ANKRD13A gene. This alteration results from a C to T substitution at nucleotide position 673, causing the arginine (R) at amino acid position 225 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
