DICER1 and miRNA-Processing Gene VCEP
The NM_177438.3:c.192A>T variant in DICER1 is a missense variant predicted to cause substitution of leucine by phenylalanine at amino acid 64 (p.Leu64Phe). Although this variant has been observed in germline cases, to our knowledge, this variant has not been reported in individuals with DICER1-related tumor predisposition (PS4 not met; PMID: 28562508, Internal lab contributors). 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: Ambry, LabCorp Genetics). The total allele frequency in gnomAD v4.1.0 is 0.000003098 (5/1613934 alleles) with a highest population minor allele frequency of 0.00001335 (1/74926 alleles) in the African/African American population and with multiple alleles present in the European (non-Finnish) population (PM2_Supporting, BS1, and BA1 are not met). In silico tools predict no damaging impact of the variant on protein function (REVEL: 0.432; MaxEntScan and SpliceAI: no effect on splicing) (BP4). 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. (Bayesian Points: -2; VCEP specifications version 1.3.0; 01/07/2025)
