Anyone else have this? It doesn't appear to be so typical with myotonia congenita.

I've suspected that my family might have a freakish new, undocumented channelopathy mutation that's some other, special freakish myotonia that's very similar to MC but not quite. That suspicion is getting stronger.

Also, after the squeeze/handshake test, my hands shake uncontrollably and are stiff to an observer (I can't really tell they're stiff except that they don't respond right), but they don't curl up in the classic myotonia congenita way.

Hmmmmm.

Type of Myotonia: Thomsen's

Country: USA
