ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PM4

Nonframeshift variant in NON repetitive region in NM_032930.3.

BS1

Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.000086 (119/1383640) while in subpopulation MID AF= 0.000878 (5/5692). AF 95% confidence interval is 0.000346. There are 0 homozygotes in gnomad4_exome. There are 58 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Collection Method: clinical testing

This variant, c.24_29dup, results in the insertion of 2 amino acid(s) of the C11orf70 protein (p.Leu9_Gly10dup), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs753634626, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with C11orf70-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
