Can you supply more information on which variant you mean? The number g.3235 is not specific enough. That would be a genomic position and not cDNA. What nucleotide has this become? E.g. a code like c.123C>T would be needed. Pref. together with the gene-version-number.
NB MSUD is a autosomal recessive disease, meaning that your variant should be present on both copies (homozygote) or there be a extra, independent variant (compound heterozygosity). Having contact with a genetic counselor is relevant when your question relates to a actual patient.
