Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BS2_SupportingBP4

This summary comes from the ClinGen Evidence Repository: The NM_177438.2:c.128C>T variant in DICER1 is a missense variant predicted to cause substitution of threonine by methionine at amino acid 43 (p.Thr43Met). This variant has been seen in 10 or more unrelated females without tumors through age 50 in at least one testing laboratory (BS2_Supporting; Internal lab contributors). In silico tools predict no damaging impact of the variant on protein function (REVEL: 0.429; MaxEntScan and SpliceAI: no effect on splicing) (BP4). The highest population minor allele frequency in gnomAD v4.1.0 is 0.0002667 (16/59982 alleles) in Admixed American population (PM2_Supporting, BS1, and BA1 are not met). In summary, this variant meets the criteria to be classified as Likely Benign for DICER1-related tumor predisposition based on the ACMG/AMP criteria applied, as specified by the ClinGen DICER1 VCEP: BS2_Supporting, BP4.

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.
