The p.C618Y pathogenic mutation (also known as c.1853G>A), located in coding exon 10 of the RET gene, results from a G to A substitution at nucleotide position 1853. The cysteine at codon 618 is replaced by tyrosine, an amino acid with highly dissimilar properties. This variant has been reported in multiple individuals diagnosed with medullary thyroid carcinoma (MTC) and/or MEN2A (Frank-Raue K et al. Hum Mutat. 2011 Jan;32(1):51-8; Landsvater RM et al. Hum Genet. 1996 Jan;97(1):11-4; Quayle FJ et al. Surgery 2007 Dec;142(6):800-5; discussion 805.e1; Zhao JQ et al. Hered Cancer Clin Pract. 2015 Jan;13(1):5). In addition, several other missense alterations that change the cysteine at codon 618 have been reported in the literature as disease-causing mutations (Landsvater RM et al. Hum Genet. 1996 Jan;97(1):11-4). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). The American Thyroid Association categorizes alterations to the C618 residue, including p.C618Y, in the B-level risk group and has made mutation specific guidelines available (Kloos RT et al. Thyroid 2009 Jun; 19(6):565-612). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. (less)

This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 618 of the RET protein (p.Cys618Tyr). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with multiple endocrine neoplasia type 2A and familial medullary thyroid cancer (PMID: 8103403, 20516206, 21765987, 25628771). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 24901). 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. Experimental studies have shown that this missense change affects RET function (PMID: 7824936, 9174404, 9230192, 9879991). This variant disrupts the p.Cys618 amino acid residue in RET. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 7915165, 9384613, 9498388, 9839497, 20979234, 22068382; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. (less)

Variant summary: RET c.1853G>A (p.Cys618Tyr) results in a non-conservative amino acid change located at a critical residue within the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 249080 control chromosomes. c.1853G>A has been widely reported in the literature in multiple individuals affected with Multiple Endocrine Neoplasia Type 2/Familial Medullary Thyroid Carcinoma and subsequently cited by others (example, Donis-Keller_1993, Chiefari_1998, Beldjord_1995, Kimura_1995, Landsvater_1996). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function. The most pronounced variant effect results in transforming activity of the RET proto-oncogene and reduced cell surface expression suggesting the potential to develop Hirschsprung's disease in addition to MEN 2A and FMTC (Ito_1997). Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as pathogenic citing overlapping evidence utilized in the context of this evaluation. Based on the evidence outlined above, the variant was classified as pathogenic. (less)

NM_020975.6(RET):c.1853G>A (p.Cys618Tyr) is a missense variant that results in the substitution of cysteine with tyrosine. The affected residue or protein region has prior evidence supporting clinical relevance. Segregation evidence has been reported in affected families. This variant has been recurrently observed in individuals with related phenotype (PMID: 8103403; PMID: 19469690; PMID: 25628771; PMID: 7824936; PMID: 9174404). Multiple computational predictions support a deleterious effect on the gene or gene product. The variant is present at low frequency in population datasets. Based on the available data, this variant is classified as pathogenic. (less)

The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number.
