Evidence submitted by expert panel
DICER1 and miRNA-Processing Gene VCEP
The NM_177438.2:c.4189T>C variant in DICER1 is a missense variant predicted to cause substitution of tryptophan by arginine at amino acid 1397 (p.Trp1397Arg). The highest population minor allele frequency in gnomAD v3.1.2 is 0.00002462 (1/40622 alleles) in African/African American population (PM2_Supporting, BS1, and BA1 are not met). 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: 61756, 500031). In silico tools predict no damaging impact of the variant on protein function (REVEL: 0.207; 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 1.2.0; 01/09/2024)
