Summary of posterior polymorphous corneal dystrophy study families and subjects.

Number of phenotyped and genotyped affected family members, unaffected first degree relatives and spouses included in this study. Presence of shared haplotype across 20p12.1- 20q12 spanning over 23 Mb as well as the core mini-haplotype at 20p12.1-20p11.23 in affected individuals, previous molecular genetic analysis and geographical origin within the Czech Republic of the eldest family member known to be affected is also shown.N = No, Y = yes.Linkage analysis for families 1 and 2 was reported in Gwilliam et al. [11]. Results of previous candidate gene screening in families 15–19 has been reported in Liskova et al. [23].
