Variant summary

Our verdict is Benign. The variant received -10 ACMG points: 0P and 10B. BP4_ModerateBS1BS2

The NM_177438.3(DICER1):c.3371A>C(p.His1124Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000434 in 1,614,170 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H1124R) has been classified as Uncertain significance. The gene DICER1 is included in the ClinGen Criteria Specification Registry.

Genes affected

DICER1 (HGNC:17098): (dicer 1, ribonuclease III) This gene encodes a protein possessing an RNA helicase motif containing a DEXH box in its amino terminus and an RNA motif in the carboxy terminus. The encoded protein functions as a ribonuclease and is required by the RNA interference and small temporal RNA (stRNA) pathways to produce the active small RNA component that represses gene expression. This protein also acts as a strong antiviral agent with activity against RNA viruses, including the Zika and SARS-CoV-2 viruses. Alternative splicing results in multiple transcript variants.

ACMG classification

Specifications for DICER1 are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.23791909).

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000131 (2/152324) while in subpopulation SAS AF = 0.000414 (2/4830). AF 95% confidence interval is 0.0000729. There are 0 homozygotes in GnomAd4. There are 1 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAdExome4 at 5 AD,Unknown gene.
