Genetic features of solved MFRP families. (a) Pedigree and haplotype analysis of F1 nanophthalmos family carrying MFRP variants (M1,M2). Boxes mark recombinant individuals. The minimal non-recombinant interval is bounded by exm2267281 and rs676943 and includes the MFRP gene. (b) Whole genome multi-point linkage analysis of F1 showing peaks on chr 6p and 11q with suggestive linkage. The chr11q peak contains the MFRP gene. (c) Sequencing chromatograms showing presence of both MFRP variants (c.498delC and c.1022T>C) in affected individuals, and only one variant in unaffected parents or children. (d) Pedigrees and variants identified in MFRP based on transcript NM_031433.4. Samples available for genotyping are included with their genotypes. (e) Protein diagram of MFRP showing location of all identified variants in this study. Frameshifts (triangle), splice altering (square), and missense (circle) variants are marked, with magenta being variants newly described in this study. (f) Homology modeling of missense variants in MFRP showing critical interactions of C285, L341, and G210. +, sampled individuals; arrow, proband.
