Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP4BP6
The NM_020975.6(RET):c.1013C>T(p.Thr338Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000192 in 1,613,700 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).

This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 338 of the RET protein (p.Thr338Ile). This variant is present in population databases (rs377767433, gnomAD 0.005%). This missense change has been observed in individual(s) with Hirschsprung's disease and micromedullary thyroid carcinoma (PMID: 11955539, 21810974). ClinVar contains an entry for this variant (Variation ID: 38594). 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 tolerated. Experimental studies have shown that this missense change does not substantially affect RET function (PMID: 21810974, 25440022). 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. -
not provided Uncertain:1
In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 12939698, 19183406, 11955539, 21810974, 21054478, 20516206, 25440022, 28946813, 30624503, 14633923, 31510104, 35264596) -
Multiple endocrine neoplasia type 2B Benign:1
- -
Hereditary cancer-predisposing syndrome Benign:1
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. -
