Description

Journal ArticlePURPOSE: A 5-bp deletion in ELOVL4, a photoreceptor-specific gene, has been associated with autosomal dominant (ad) macular dystrophy phenotypes in five related families, in which phenotypes range from Stargardt-like macular dystrophy (STGD3; Mendelian Inheritance in Man 600110) to pattern dystrophy. This has been the only mutation identified in ELOVL4 to date, which is associated with macular dystrophy phenotypes. In the current study, the potential involvement was investigated of an ELOVL4 gene variation in adSTGD-like and other macular dystrophy phenotypes segregating in a large unrelated pedigree from Utah (K4175). METHODS: The entire open reading frame of the ELOVL4 gene was analyzed by direct sequencing in a proband from the K4175 family. The combination of denaturing high-performance liquid chromatography (DHPLC) analysis and direct sequencing of all available family members was used to further assess segregation of identified ELOVL4 variants in the pedigree.
