      The variant was c.52C>T (p.Arg18Trp).

      PMID:39398711

      Gene: ABCA4

      HGNC ID: 34

      Case Annotation Template

      Case#: 19-year-old male

      DiseaseAssertion: Stargardt disease 1 (STGD1)

      FamilyInfo: No family history of eye disease reported. Autosomal recessive inheritance consistent with STGD1. Homozygous ABCA4 variant identified.

      CasePresentingHPOs: DecreasedCentralVA, MacularAtrophy, MacularFlecks, PeripapillarySparing, OpticNervePallor

      CaseHPOFreeText: Five-year history of progressive bilateral central vision loss, worse at near. Alternating exotropia measuring 16 prism diopters in all gazes OU. Best corrected visual acuity 20/200 OU. Fundus examination revealed pigment deposition and macular mottling. Fundus autofluorescence showed central decreased autofluorescence surrounded by increased autofluorescence. Fluorescein angiography demonstrated dark choroid. OCT showed loss of the central ellipsoid zone with hyperreflective deposits. Multifocal ERG demonstrated significant functional loss.

      CaseNotHPOs: NightBlindness

      CaseNotHPOFreeText: Patient denied nyctalopia, photophobia, or flashes. Color vision normal on Ishihara testing.

      Genotyping Method: Genotyping Method: Next-generation sequencing (NGS) with deletion/duplication analysis (Invitae Corporation).
