  • And again that for these myotonias, these mutations are in the skeletal isoform of the sodium channel.
  • different isoforms
  • two isoforms
  • splice isoform

Now today we realize that there's a clear stratification of risk when it comes to Alzheimer's disease that tracks with those isoforms.

Examples

  • The finding that FST 315 is the predominant circulating FST isoform in human serum supports this concept.

Morphology

isoform = form (semi-transparent) = iso + form

The combining form 'iso-' is technical and used in scientific vocabulary; while 'form' is clear, the precise biological sense ('variant of the same protein') requires domain knowledge.

Etymology

Isoform comes from iso- and form, where iso- means 'equal' and form means 'shape' or 'type', the same form you see in the word uniform. So an isoform is like a 'same-type' version of a protein or molecule: it comes from the same gene and works in a similar way but with small differences.
