ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.011102408).

BP6

Variant 2-196001709-A-C is Benign according to our data. Variant chr2-196001709-A-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 402759.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00894 (1361/152312) while in subpopulation NFE AF = 0.0136 (924/68028). AF 95% confidence interval is 0.0129. There are 5 homozygotes in GnomAd4. There are 609 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 5 AR gene
