Notes
rs186031457, also known as c.337C>T, p.Arg113Ter and R113X, represents a rare mutation in the PCCB gene on chromosome 3. The minor allele is reported by a single submitter in ClinVar as being pathogenic for propionic acidemia, a recessively inherited condition.
C;T
Unaffected in absence of a second pathogenic mutation elsewhere in the PCCB gene; see discussion at rs186031457
