Genes affected

DRD2 (HGNC:3023): (dopamine receptor D2) This gene encodes the D2 subtype of the dopamine receptor. This G-protein coupled receptor inhibits adenylyl cyclase activity. A missense mutation in this gene causes myoclonus dystonia; other mutations have been associated with schizophrenia. Alternative splicing of this gene results in two transcript variants encoding different isoforms. A third variant has been described, but it has not been determined whether this form is normal or due to aberrant splicing. [provided by RefSeq, Jul 2008]

The c.1292T>C (p.I431T) alteration is located in exon 8 (coding exon 7) of the DRD2 gene. This alteration results from a T to C substitution at nucleotide position 1292, causing the isoleucine (I) at amino acid position 431 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 431 of the DRD2 protein (p.Ile431Thr). This variant has not been reported in the literature in individuals affected with DRD2-related conditions. This variant is present in population databases (rs376186482, gnomAD 0.04%), and has an allele count higher than expected for a pathogenic variant. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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. -
