ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -17 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.74).
BP6
Variant 22-50221635-C-T is Benign according to our data. Variant chr22-50221635-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 437154.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-0.073 with no splicing effect.
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000473 (72/152308) while in subpopulation AMR AF = 0.00118 (18/15312). AF 95% confidence interval is 0.00076. There are 0 homozygotes in GnomAd4. There are 40 alleles in the male GnomAd4 subpopulation. Median coverage is 34. This position passed quality control check.
