To access the data, click or select the words “Appendix 2.” The haplotypes, represented by vertical bars, are composed of three single nucleotide polymorphisms (SNPs) flanking the c.1146+5G>T allele of the PRPF31 gene, on chromosome 19q13.42. SNP order and genomic coordinates are indicated to the right. The c.1146+5G>T-bearing haplotype is marked in red. Paternal haplotypes (in brackets) were reconstructed based on genotypes of individuals 1, 5, 6 and 7, but not molecularly confirmed. Individuals 5 and 7 inherited different paternal chromosomes.
