General characterization of germline variants in individuals with keratoconus (KC) and controls. a Distribution of indels and single nucleotide variants (SNVs) across the four minor allele frequency (MAF) bins. The bin of ‘‘MAF < 0.05’’ excludes singletons and doubletons. b Fraction of variants annotated by RefSeq genomic functions across the four MAF bins. The bin of ‘‘MAF < 0.05’’ excludes singletons and doubletons. c Principal Component Analysis plot comparing KC individuals with populations from the 1000 Genomes Project. d Fraction of exonic variants annotated by the Variant Effect Predictor (VEP). e Distribution of the prevalence of pathogenic alleles among cases. B-mis: benign missense; D-mis: damaging missense; PTVs: protein-truncating variants; Syn: synonymous
