Figure 4. Haplotype analysis of the single nucleotide polymorphism (SNP’s) surrounding the MER protein kinase (MERTK) gene in Family A. Haplotyped pedigree of Family A showing the segregation of the deletion with the surrounding SNPs (rs ID numbers to the left of the haplotype) used to map the family to this region. The proband (IV:2, patient 1) is marked by an arrow. The black bar represents the disease haplotype.
