Variant chr2-70979208-G-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001115116.2(ANKRD53):c.282G>C(p.Lys94Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000205 in 1,460,954 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 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. K94E) has been classified as Likely benign.

The c.282G>C (p.K94N) alteration is located in exon 2 (coding exon 2) of the ANKRD53 gene. This alteration results from a G to C substitution at nucleotide position 282, causing the lysine (K) at amino acid position 94 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
