WebWhat is the difference between FSHD1 and FSHD2? Expand. FSHD2 is clinically identical to FSHD1 but genetically distinct. In FSHD1, the tandem repeats called D4Z4 on chromosome 4 are deleted, whereas in FSHD2, the number of D4Z4 repeats is in the normal range. Another way of saying this is that there is no “contraction” in D4Z4 at 4q35. WebNov 1, 2024 · FSHD1 is characterised by a DZ4Z repeat array contraction to less than 11 units, on a background of the permissive 4qA allele, while FSHD2 is characterised by a low-normal-sized D4Z4 array and the presence of additional mutations in chromatin modifier genes (for example SMCHD1, DNMT3B and LRIF1 ), also on a 4qA background.
