Genetic features of solved PRSS56 families. (a) Pedigree and haplotype analysis of F8 showing minimal area of homozygosity bounded by rs1435850 and exm2269383. Major allele is marked as A and minor allele marked as B, with PRSS56 variant indicated by M, and proband indicated by the arrow. (b) Sequencing chromatograms showing segregation of two missense p.(T142K) and p.(A169E) variants among all affected individuals. (c) Pedigrees and variants identified in other solved families. Black shading indicates phenotyped affected individuals, while gray shading indicates familial report of affected status or thick glasses. (d) Protein diagram of PRSS56 showing location of all identified variants in this study. Frameshifts (triangle), splice altering (square), and missense (circle) variants are marked; magenta shows newly described variants. (e) Homology modeling of PRSS56. + , sampled individuals.
