Genes affected
RET (HGNC:9967): (ret proto-oncogene) This gene encodes a transmembrane receptor and member of the tyrosine protein kinase family of proteins. Binding of ligands such as GDNF (glial cell-line derived neurotrophic factor) and other related proteins to the encoded receptor stimulates receptor dimerization and activation of downstream signaling pathways that play a role in cell differentiation, growth, migration and survival. The encoded receptor is important in development of the nervous system, and the development of organs and tissues derived from the neural crest. This proto-oncogene can undergo oncogenic activation through both cytogenetic rearrangement and activating point mutations. Mutations in this gene are associated with Hirschsprung disease and central hypoventilation syndrome and have been identified in patients with renal agenesis. [provided by RefSeq, Sep 2017]

Likely benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpJun 21, 2021Variant 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. -
