Abstrakt: | Mutations in protein O-mannosyltransferase 2 can cause a wide spectrum of clinical phenotypes from severe congenital muscular dystrophy such as Walker-Warburg syndrome to milder limb-girdle muscular dystrophy 2N. We aimed to describe the clinical and paraclinical features, laboratory tests, and molecular findings of four siblings with a homozygous mutation in the protein O-mannosyltransferase 2 gene. There were two sisters and two brothers, aged 4 to 17 years, with an age of onset symptoms at 3 to 12 years. The main neurologic findings were mild intellectual disability, hypoactive deep tendon reflexes, symmetrical weakness of the proximal lower and/or upper limbs, and difficulties in walking on heels and/or toes. The scoliosis found in two siblings has not been associated with protein O-mannosyltransferase 2 gene mutations related to limb-girdle muscular dystrophy 2N in previous reports. This report expands the phenotypic spectrum of protein O-mannosyltransferase 2 gene mutation-related limb-girdle muscular dystrophy 2N.
