Does pregnancy cause health issues in a woman with paramyotonia congenita?

There is limited information in the medical literature regarding the effects of pregnancy in individuals with paramyotonia congenita, as this condition is quite rare.  One article described the experience of four women with this condition: one experienced worsening of her symptoms during pregnancy, whereas three did not.[1]  Another article on paramyotonia congenita and related conditions listed pregnancy as a possible trigger of muscle weakness in affected women.[2]  Though there is little information about pregnancy in women with paramyotonia congenita, general information about women affected by other myotonia conditions suggests symptoms may worsen during pregnancy, but quickly return to usual levels after pregnancy.[3]
