ABCA4 gene associated retinal dystrophies (ABCA4-RD) are a group of inherited eye diseases caused by ABCA4 gene mutations, including Stargardt disease, cone-rod dystrophy and retinitis pigmentosa. With the development of next-generation sequencing (NGS), numerous clinical and genetic studies on ABCA4-RD have been performed, and the genotype and phenotype spectra have been elucidated. However, most of the studies focused on the Caucasian population and limited studies of large Chinese ABCA4-RD cohorts were reported. In this study, we summarized the phenotypic and genotypic characteristics of 129 Chinese patients with ABCA4-RD. We found a mutation spectrum of Chinese patients which is considerably different from that of the Caucasian population and identified 35 novel ABCA4 mutations. We also reported some rare and special cases, such as, pedigrees with patients in two generations, patients diagnosed with cone-rod dystrophy or retinitis pigmentosa, patients with subretinal fibrosis and patients with preserved foveal structure. At the same time, we focused on the correlation between the genotypes and phenotypes. By the comprehensive analysis of multiple clinical examinations and the application of multiple regression analysis, we proved that patients with two “null” variants had a younger onset age and reached legal blindness earlier than patients with two “likely-functional” variants. Patients with one or more missense variants tended to have better visual acuity and presented with milder fundus autofluorescence changes and more preserved rod functions on the full-field electroretinography than patients with two “null” variants. Furthermore, most patients with the p.(Phe2188Ser) variant shared a mild phenotype with a low fundus autofluorescence signal limited to the fovea and with normal full-field electroretinography responses. Our findings expand the variant spectrum of the ABCA4 gene and enhance the knowledge of Chinese patients with ABCA4-RD.
