Abstract

Although stuttering is known to be a familial disorder, no clear evidence regarding precise mode of transmission has arisen from previous research. In this report segregation analysis is applied to data on 386 stuttering probands and their first‐degree relatives in an effort to discriminate among possible genetic models for the transmission of stuttering. Two different segregation analysis programs, PAP and POINTER, gave comparable results with respect to both hypothesis testing and parameter estimation. Specifically, the transmission of stuttering observed in these families cannot be adequately explained by a Mendelian major locus. The hypothesis of no polygenic component in the transmission of stuttering can, however, be rejected. Existence in these data of potential heterogeneity and possible violations of assumptions concerning ascertainment are considered in interpreting the results.
