Biallelic loss‐of‐function mutations in the encoding gene MEGF10 cause a recessive congenital muscle disease called MEGF10 myopathy [1, 2, 3, 4, 5, 6, 7]; the classic form of this disease is also known as early onset myopathy with areflexia, respiratory distress, and dysphagia (EMARDD) [8]. Here, MEGF10 is linked to Areflexia.
