Fig. 6. Predicting consequences of missense variants in HPRT1.

Fig. 6

A Structure of HPRT1 shown as van der Walls surfaces with the predicted functional residues coloured in blue. Residues which contain at least one disease-causing variant are labelled and coloured according to which diseases it has been associated with (see legend). B Yeast-based assay for HPRT1 function. Yeast strains carrying a vector control, wild-type HPRT1 or one of the 17 HPRT1 variants all grow on medium containing guanine. In the presence of the inosine monophosphate dehydrogenase inhibitor mycophenolic acid (MPA), yeast cells cannot grow in the absence of a functional HPRT1 protein. C Assessment of protein abundance using western blots of the 6His-tagged HPRT1 variants. D Comparing predictions of the effects of the variants with the experimental measurements. Rosetta ΔΔG values are in units of kcal/mol. Panels B and C show representative results of three replicates. Source data for this figure are provided as a Source Data File.
