Variant 14-95124432-C-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP7BP4

This summary comes from the ClinGen Evidence Repository: The NM_177438.2:c.1140G>C (p.Leu380=) variant is a synonymous (silent) variant that is not predicted to impact splicing by MaxEntScan or SpliceAI (BP4, BP7). The total allele frequency in gnomAD v4.1.0 is 0.000006195 (10/1614118alleles) with a highest population minor allele frequency of 0.00008783 (8/91086alleles) in the South Asian 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: BP4, BP7. (Bayesian Points: -2; VCEP specifications version 1.3.0; 06/28/2024) LINK:https://erepo.genome.network/evrepo/ui/classification/CA7331523/MONDO:0100216/024

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.

Uncertain significance, criteria provided, single submitter	curation	Sema4, Sema4	Feb 10, 2022	- -
Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 27, 2017	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
