CACNA1F and congenital stationary night blindness: The p.Ser429Phe variant was found in a small trio exome sequencing cohort, in a young child with high myopia.13 This individual also carried a hemizygous missense variant in CACNA1F (NP_005174.2: p.[Arg1060Trp]), which has already been described as a pathogenic variant causing X-linked congenital stationary night blindness (MIM 300071), possibly explaining the phenotype in this individual.
