Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_032806.6(POMGNT2):c.1384C>T(p.Arg462Trp) variant causes a missense change. The variant allele was found at a frequency of 0.00131 in 1,613,824 control chromosomes in the GnomAD database, including 25 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R462Q) has been classified as Uncertain significance.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.00639081).

BP6

Variant 3-43080048-G-A is Benign according to our data. Variant chr3-43080048-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 386897.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00706 (1076/152342) while in subpopulation AFR AF = 0.0242 (1006/41588). AF 95% confidence interval is 0.0229. There are 14 homozygotes in GnomAd4. There are 525 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 14 AR gene
