Variant summary
Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BP4_StrongBP6BS1
The NM_020975.6(RET):c.1157C>T(p.Ala386Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000154 in 1,613,872 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

Variant summary: The variant, RET c.1157C>T (p.Ala386Val) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00026 in 277152 control chromosomes, predominantly at a frequency of 0.0025 within the African subpopulation in the gnomAD database. The observed variant frequency within African control individuals in the gnomAD database is approximately 68 fold of the estimated maximal expected allele frequency for a pathogenic variant in RET causing Multiple Endocrine Neoplasia Type 2 phenotype (3.7e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African origin. The variant, c.1157C>T has been reported in the literature in individuals affected with Hirschsprung's disease (Carter_2012). However, this report does not provide unequivocal conclusions about association of the variant with Multiple Endocrine Neoplasia Type 2. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (2X Likely Benign and 1X Uncertain Significance). Based on the evidence outlined above, the variant was classified as likely benign. -

not provided Uncertain:1Benign:1

- -
Hereditary cancer-predisposing syndrome Benign:2
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. -
- -
Multiple endocrine neoplasia, type 2 Benign:1
- -
RET-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
