Additionally, CMD can present with various complex phenotypes, which can be categorised into several distinct subtypes on the basis of their characteristics as follows: merosin‐deficient CMD type 1A (MDC1A), merosin‐deficient CMD type 1B (with muscle hypertrophy and respiratory failure) (MDC1B), merosin‐deficient congenital muscular dystrophy type 1C (with muscle hypertrophy) (MDC1C), merosin‐deficient congenital muscular dystrophy type 1D (with intellectual disability and abnormal glycosylation) (MDC1D) and CMD with cardiomyopathy, etc. [10, 11, 12, 13]. Here, LAMA2 is linked to hypertrophy.
