ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -21 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.53).

BP6

Variant 18-45949582-G-A is Benign according to our data. Variant chr18-45949582-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 534615.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=2.28 with no splicing effect.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00753 (1145/152118) while in subpopulation SAS AF = 0.0139 (67/4820). AF 95% confidence interval is 0.0112. There are 9 homozygotes in GnomAd4. There are 544 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 9 AR gene
