ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.015889406).
BP6
Variant 22-50243805-C-A is Benign according to our data. Variant chr22-50243805-C-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 437161.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.000423 (618/1461440) while in subpopulation MID AF= 0.00364 (21/5766). AF 95% confidence interval is 0.00244. There are 1 homozygotes in gnomad4_exome. There are 325 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.

Inborn genetic diseases Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
