Variant summary

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

The NM_001371928.1(AHDC1):c.286C>T(p.Arg96Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00047 in 1,611,796 control chromosomes in the GnomAD database, including 4 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. R96H) has been classified as Likely benign.

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (MetaRNN=0.0062986016).

BP6

Variant 1-27551830-G-A is Benign according to our data. Variant chr1-27551830-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 377337.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 = 0.00238 (362/152034) while in subpopulation AFR AF = 0.0083 (344/41454). AF 95% confidence interval is 0.00758. There are 1 homozygotes in GnomAd4. There are 182 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 362 AD gene.
