Cím:Identification of a novel deletion in the ABCC6 gene leading to Pseudoxanthoma elasticum / Katona E., Aslanidis C., Remenyik E., Csikós M., Kárpáti S., Paragh G., Schmitz G.
Dátum:2005
Megjegyzések:Pseudoxanthoma elasticum (PXE) is an inherited systemic disorder, characterized by dermal, ocular and cardiovascular lesions. Genetic defects of the ABCC6 (MRP6) transporter are known to cause PXE. OBJECTIVES: The purpose of this study was to identify the genetic background of a PXE patient with a very early onset of the disease and severe systemic involvement. METHODS: Direct sequencing of genomic DNA obtained from peripheral whole blood.RESULTS: Our patient was found to be compound heterozygous with both ABCC6 alleles having genomic deletions. A novel exon 24-25 deletion was identified on one allele, while the frequently observed exon 23-29 deletion was found on the other allele. The novel deletion is 4.68 kb long and was shown to extend from intron 23 to 25. DNA-sequencing of a 2.03 kb fusion fragment revealed the deletion breakpoints within introns 23 and 25 originating in the middle of two Alu-repeats. CONCLUSION: In a patient with severe clinical symptoms, we found two genomic deletions in regions that might be important for function of the ABCC6 transporter. Genomic deletions in ABCC6 may occur more frequently in PXE patients than previously expected and future genetic analysis should focus on these mutations as well.
