      Variant: c.3113C>T p.(Ala1038Val)

      ClinVar: https://www.ncbi.nlm.nih.gov/clinvar/variation/7894/

      SupplementalData: MFSD8 variants identified

  2. Feb 2026
    1. There were no pathogenic variants or variants of unknown significance identified. Genes included in the testing: ABCA4

      Case report no known pathogenic variants of ABCA4 found. subject had a diagnosis of stargardt disease

    1. Sequencing of the coding region of ABCA4 and of the entire ABCA4 locus revealed one heterozygous ABCA4 variant c.3113C>T; p.(Ala1038Val). No other (likely) pathogenic coding or noncoding ABCA4 variants including copy number variants were identified.

      ABCA4 variant revealed but not target of research and doesn't seem to amount to anything Variantc.3113C>T p.(Ala1038Val)

    1. variant in exon 44 presented with contrasting phenotypes; from early‐onset cone‐rod dystrophy

      Deletion on exon 44 resulting in dystrophy of parts of eye
