This variant is present in population databases (rs774449661, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with TRDN-related conditions. ClinVar contains an entry for this variant (Variation ID: 659814). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0". The alanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. (less)

Comment:

This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 722 of the TRDN protein (p.Pro722Ala). This variant is present in population databases (rs774449661, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with TRDN-related conditions.

The alanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.

Comment:

Has not been previously published as pathogenic or benign to our knowledge; Not observed at significant frequency in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 26582918)

Comment:

The p.P722A variant (also known as c.2164C>G), located in coding exon 41 of the TRDN gene, results from a C to G substitution at nucleotide position 2164. The proline at codon 722 is replaced by alanine, an amino acid with highly similar properties. This amino acid position is conserved. 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.
