The truth that the highest linkage scores were obtained for the GNPTAB G3598A variant, combined with the insufficient various other plausible genetic variants within the linkage interval, recommended that this variant increases the threat of stuttering when within either one or two copies. We then screened because of this and various other potential mutations in GNPTAB in additional affected, unrelated Pakistani people, including 1 affected member from each one of the 46 households analyzed in our previous linkage study,12 and in 96 unaffected matched Pakistani control subjects. This mutation thus appears to be most typical in populations from the Asian subcontinent. We determined three additional potential mutations in four affected, unrelated topics, as summarized in Table 1Table 1Mutations Found in GNPTAB, GNPTG, and NAGPA.
