Abstract

Mutations in A-type nuclear lamins are known to cause a variety of diseases, which can affect almost all organs of the human body including striated muscle. For lamin-related congenital muscular dystrophy two different phenotypes are known to date.

In addition to this novel mutation, the patient also had cerebral white matter lesions on MRI and cognitive impairment on developmental testing. This is only the second A-type lamin-related congenital muscular dystrophy patie..
