Variant summary

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

The NM_001145210.3(ANKRD65):c.932G>A(p.Arg311Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00002 in 1,550,108 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/15 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. R311W) has been classified as Uncertain significance.

The c.932G>A (p.R311Q) alteration is located in exon 4 (coding exon 3) of the ANKRD65 gene. This alteration results from a G to A substitution at nucleotide position 932, causing the arginine (R) at amino acid position 311 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
