ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

BP4

Computational evidence support a benign effect (REVEL=0.005).

BP6

Variant 22-50227038-C-T is Benign according to our data. Variant chr22-50227038-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 437167.

BP7

Synonymous conserved (PhyloP=-2.49 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00101 (154/152282) while in subpopulation AFR AF = 0.00344 (143/41548). AF 95% confidence interval is 0.00298. There are 0 homozygotes in GnomAd4. There are 78 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
