This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 4 of the RET protein (p.Ala4Thr). This variant is not present in population databases (gnomAD no frequency). 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: 1023866). 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 alanine with threonine at codon 4 of the RET protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with RET-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD).

The p.A4T variant (also known as c.10G>A), located in coding exon 1 of the RET gene, results from a G to A substitution at nucleotide position 10. The alanine at codon 4 is replaced by threonine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. (less)

Record last updated Sep 29, 2024
This date represents the last time this VCV record was updated. 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. So this date may be different from the date of the “most recent submission” reported at the top of this page.
