Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_020975.6(RET):c.178C>A(p.Pro60Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P60L) has been classified as Uncertain significance.

Multiple endocrine neoplasia, type 2 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 09, 2019 | Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a RET-related disease. This sequence change replaces proline with threonine at codon 60 of the RET protein (p.Pro60Thr). The proline residue is moderately conserved and there is a small physicochemical difference between proline and threonine. In summary, this variant is a novel missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 28, 2023 | The p.P60T variant (also known as c.178C>A), located in coding exon 2 of the RET gene, results from a C to A substitution at nucleotide position 178. The proline at codon 60 is replaced by threonine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
