We have modified the sentence of the Fl-transcript: “All variants altered splicing, 18 of which produced no traces of the mgFL-transcript or almost undetectable levels (<2.4%, c.904G>A)…”
The acronyms need to be explained. Not all readers are familiar with PTC (premature termination codon) and NMD (nonsense mediated decay); as some variants are found PTC-NMD, this needs to be explained better. I would also stress a little more that FL is almost undetectable.
