Notes
rs137853822, also known as c.1363G>T, Ala455Ser or A455S, is a variant in the GNPTAB gene on chromosome 12. The minor (T) allele of rs137853822 was a mutation in the GNPTAB gene associated with stuttering in a 2010 study. Note that inheritance was neither dominant or recessive; this variant increased the risk of stuttering when present in either one or two copies, consistent with an additive genetic effect. Female homozygotes were apparently less affected. Note that the proportion of stutterers likely to carry a GNPTAB variant is likely to be less than 4%.
