Results are indicated as median (25th to 75th percentile).
n = 133.
n = 149.
Linkage was defined as complete cosegregation (pedigrees with no phenocopies and fully penetrant) or incomplete cosegregation (pedigrees with either phenocopies or nonpenetrance).14
n = 173.
n = 56.
n = 227.
Comprise premature stop codons caused by nonsense mutations, frame shifts (small deletions and insertions), and out-of-frame splice site mutations.
