Bold font indicates significant evidence (P ≤ 0.000048).

Note: All nonparametric linkage (NPL) scores have been converted to equivalent logarithm of the odds (LOD) scores. Chromosomal locations indicated in italics overlap our affected-only genome scan using clinical diagnosis [32].

1 Location at the maximum of the peak.

2 Alpha, the estimated proportion of linked families for the MCLINK heterogeneity LOD score, is given for parametric analyses.

3 The peak at 9p24.3 is in the same location as a peak reported in a single family from our sample [35].

4 The peak at 11p15.1-p15.4 replicates previous genome scan results of quantitative SRS scores [20].
