question: What is the genomic structure of the FAA (FANCA) gene?
answer: The FAA (FANCA) gene contains 43 exons spanning approximately 80 kb. Exons range from 34 to 188 bp, whereas sequence analysis of the 5' region upstream of the putative transcription start site showed no obvious TATA and CAAT boxes, but did show a GC-rich region, typical of housekeeping genes.
