ACHM: Achromatopsia; ad: autosomal dominant; ar: autosomal recessive; BMD: best macular disease; Comp Het: compound heterozygous; ESE: exonic splicing enhancer; ESS: exonic splicing silencer; Hem: Hemizygous; Het: heterozygous; Hom: homozygous; LCA: Leber Congenital Amaurosis; nd IRD: inherited retinal degeneration not otherwise specified without precisely defined diagnosis; RP: Retinitis Pigmentosa; STGD: Stargardt Disease; USH: Usher Syndrome; wt: wild-type; xl: X-linked. For nonsynonymous variants, predictions from dbNSFP are reported, comprising scores from the following alghoritms: SIFT | Polyphen2HDIV Polypehn2HVAR | LRT | MutationTaster | MutationAssessor | FATHMM | MetaSVM | MetaLR | PROVEAN | fathmm-MKL. For splicing variants, predictions from Human Splicing Finder, dbscSNV (ada_score|rf_score) and SPIDEX are reported. For SPIDEX, max dPSI is shown if lower than −1 (maximum mutation − induced change in the percentage of transcripts with the exon spliced in). Familiar case: the patients were from the same family. *Sanger sequencing was performed to confirm mutation frequency.
