Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_020964.3(EPG5):​c.4039A>C​(p.Asn1347His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00529 in 1,614,114 control chromosomes in the GnomAD database, including 33 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N1347S) has been classified as Uncertain significance.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0058216155).
BP6
Variant 18-45910687-T-G is Benign according to our data. Variant chr18-45910687-T-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 225029.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00397 (605/152262) while in subpopulation NFE AF = 0.00629 (428/68024). AF 95% confidence interval is 0.0058. There are 1 homozygotes in GnomAd4. There are 290 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 32 AR gene
