Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP4BP6
The NM_020975.6(RET):c.1124T>A(p.Leu375Gln) variant causes a missense change. The variant allele was found at a frequency of 0.000111 in 1,613,722 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. L375L) has been classified as Likely benign.

Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 15, 2020 | 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. - |

Likely benign, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Jun 21, 2021 | Variant summary: RET c.1124T>A (p.Leu375Gln) results in a non-conservative amino acid change located in the Tyrosine-protein kinase receptor Ret, cadherin like domain 3 (IPR040667) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00013 in 250980 control chromosomes, predominantly at a frequency of 0.0019 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 51 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 or African-American origin. c.1124T>A has been reported in the literature as a VUS in settings of multigene cancer panel testing among individuals affected with a variety of cancers such as high grade glioma, T-cell ALL and in the TGCA cohort (example, Zhang_2018, Yehia_2018). These report(s) do 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. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments (likely benign, n=2; VUS, n=2). Based on the evidence outlined above, the variant was classified as likely benign. - |
