Genes affected

PDE10A (HGNC:8772): (phosphodiesterase 10A) The protein encoded by this gene belongs to the cyclic nucleotide phosphodiesterase family. It plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides. This protein can hydrolyze both cAMP and cGMP to the corresponding nucleoside 5' monophosphate, but has higher affinity for cAMP, and is more efficient with cAMP as substrate. Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Dec 2011]

The c.2356G>T (p.A786S) alteration is located in exon 22 (coding exon 22) of the PDE10A gene. This alteration results from a G to T substitution at nucleotide position 2356, causing the alanine (A) at amino acid position 786 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

ClinVar contains an entry for this variant (Variation ID: 1507084). 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with PDE10A-related conditions. This variant is present in population databases (rs753303000, gnomAD 0.007%). This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 786 of the PDE10A protein (p.Ala786Ser). -
