Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_014915.3(ANKRD26):c.92G>C(p.Gly31Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000393 in 1,612,304 control chromosomes in the GnomAD database, including 4 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G31R) has been classified as Uncertain significance.

Genes affected

ANKRD26 (HGNC:29186): (ankyrin repeat domain containing 26) This gene encodes a protein containing N-terminal ankyrin repeats which function in protein-protein interactions. Mutations in this gene are associated with autosomal dominant thrombocytopenia-2. Pseudogenes of this gene are found on chromosome 7, 10, 13 and 16. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0039687157).

BP6

Variant 10-27100235-C-G is Benign according to our data. Variant chr10-27100235-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 434205.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00186 (284/152364) while in subpopulation AFR AF = 0.0064 (266/41592). AF 95% confidence interval is 0.00576. There are 1 homozygotes in GnomAd4. There are 142 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 284 AD gene.
