Added comment: 4 unrelated European families with a heterozygous TTTCA(n) repeat expansion in intron 1 of the MARCHF6 gene. (TTTTA)n repeat is a polymorphic microsatellite with the number of TTTTA repeats ranging from 9 to 20; repeats containing TTTCA motifs were never observed in controls, indicating that the TTTCA repeats are the pathogenic part of the expansion similar to other FAMEs. Patient cells did not show any difference in MARCHF6 RNA or protein expression compared to controls, and there was no difference in the level of intron 1-containing RNA, thus excluding a massive accumulation of abnormally spliced mRNA carrying the expansion in these cells.
