ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.823

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.00000974 (14/1438032) while in subpopulation MID AF = 0.00122 (7/5724). AF 95% confidence interval is 0.000573. There are 1 homozygotes in GnomAdExome4. There are 6 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
