Target Background

Function
Flippase that catalyzes in an ATP-dependent manner the transport of retinal-phosphatidylethanolamine conjugates like the 11-cis and all-trans isomers of N-retinylidene-phosphatidylethanolamine from the lumen to the cytoplasmic leaflet of photoreceptor outer segment disk membranes, where N-cis-retinylidene-phosphatidylethanolamine (N-cis-R-PE) is then isomerized to its all-trans isomer (N-trans-R-PE) and reduced by RDH8 to produce all-trans-retinol (all-trans-rol) and therefore prevents the accumulation of excess of 11-cis-retinal and its schiff-base conjugate and the formation of toxic bisretinoid. May display both ATPase and GTPase activity that is strongly influenced by the lipid environment and the presence of retinoid compounds. Binds the unprotonated form of N-retinylidene-phosphatidylethanolamine with high affinity in the absence of ATP, and ATP binding and hydrolysis induce a protein conformational change that causes the dissociation of N-retinylidene-phosphatidylethanolamine.
Gene References into Functions
  1. neighboring deep-intronic ABCA4 variants (c.4539+2001G>A and c.4539+2028C>T) result in a retina-specific 345-nt pseudoexon insertion. PMID: 29526278
  2. Two intronic variants c.4773+3A>G and c.5461-10T>C, both predicted to affect splicing, are indeed disease-causing mutations due to skipping of exons 33, 34, 39 and 40 of ABCA4 gene. The experimental proof that ABCA4 mutations in STGD patients affect protein function is crucial for their inclusion to future clinical trials. PMID: 29461686
  3. The study broadens the spectrum of ABCA4 mutations with 60 likely pathogenic or pathogenic variants, all associated with Stargardt disease. PMID: 30060493
  4. Full-field electroretinography is a predictor of the natural course of ABCA4-associated retinal degeneration. PMID: 29386879
  5. Next-generation sequencing was effective for the molecular diagnosis of genetic diseases and specifically allowed a conclusive diagnosis in 80% (40/50) of the patients. As the ABCA4 gene does not show a preferential region for pathogenic variants, the diagnosis of Stargardt disease depends on broader analysis of the gene. The most common pathogenic variants in the ABCA4 gene described in the literature were also found. PMID: 30093795
  6. The results indicate that the p.Ala1773Val mutation in ABCA4 is associated with a severe retinal phenotype and thus, could be classified as null. PMID: 29422768
  7. The ROC phenotype is a unique classification of ABCA4 disease, which is caused by deleterious null biallelic ABCA4 mutations and is characterized by the rapid deterioration of retinal pigment epithelium and photoreceptor layers in the macula and significant choroidal thinning within the first 2 decades of life. PMID: 28947085

  18. This study describes the functional effect and the molecular mechanism of the pathogenic ABCA4 variant c.5461-10T>C. The variant is functionally important as it leads to splicing defects and a reduced level of ABCA4 protein. PMID: 27775217
  19. study to determine the effect of 15 individual ABCA4 mutations on retinal disease severity; in the hemizygous state, 2/15 ABCA4 alleles retain preserved peripheral retinal function; 7/15 are associated with either preserved or only mildly abnormal retinal function, worse in older patients; 6/15 behave like null mutations PMID: 27820952
  20. The ABCA4 variant c.5461-10T-->C is located on a founder haplotype lacking other disease-causing rare sequence variants. In vitro studies revealed that it leads to mRNA exon skipping and ABCA4 protein truncation. PMID: 26976702
  21. Genetic risk score estimates suggest that defined common ABCA4 variants influence disease risk in carriers of a single pathogenic ABCA4 allele. PMID: 28118664
  22. A combination of p.[(L541P; A1038V)] and/or a truncating ABCA4 mutation always resulted in an early disease onset.

  26. Of the 225 genetic tests performed, 150 were for recessive IRD, and 75 were for dominant IRD. A positive molecular diagnosis was made in 70 (59%) of probands with recessive IRD and 19 (26%) probands with dominant IRD.
