Multiple endocrine neoplasia, type 2 Uncertain:2
This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 1062 of the RET protein (p.Tyr1062His). This variant is present in population databases (rs138010639, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with RET-related conditions. ClinVar contains an entry for this variant (Variation ID: 823117). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
This missense variant replaces tyrosine with histidine at codon 1062 of the RET protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 4/282304 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Hereditary cancer-predisposing syndrome Uncertain:1
The p.Y1062H variant (also known as c.3184T>C), located in coding exon 19 of the RET gene, results from a T to C substitution at nucleotide position 3184. The tyrosine at codon 1062 is replaced by histidine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
RET-related disorder Uncertain:1
The RET c.3184T>C variant is predicted to result in the amino acid substitution p.Tyr1062His. This variant was reported in an individual presenting with intractable seizures (Supplemental Table 1, Chetruengchai et al 2022. PubMed ID: 34621001). A different variant impacting the same amino acid residue (p.Tyr1062Cys) has been reported in individuals with Hirschsprung disease (Wu et al. 2005. PubMed ID: 15834508). This variant is reported in 0.0080% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
