Why the study?
Suspected myotonia congenita was investigated in a flock of Merino sheep in Australia following reports of lambs that would fall on disturbance and rapidly recover.
Identification of a missense variant in CLCN1 as the likely cause of myotonia congenita in Australian Merino sheep enables diagnostic screening to reduce variant propagation.
No takes yet. Share an insight, caveat, or question.
Reports of myotonia congenita in Merino sheep extend the known species range; leaves open genetic confirmation and prevalence studies.
Manning et al. (2024) studied this question.
