SYNGR3 encodes an integral membrane protein that functions in regulated exocytosis and indirectly regulates dopamine transporter activity at synapses. The gene has moderate constraint against loss-of-function variants (LOEUF 0.746), but definitive disease associations have not been established based on the provided information. Additional clinical and genetic evidence would be needed to determine specific phenotypes and inheritance patterns associated with SYNGR3 mutations.

This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
