Background: Hereditary myopathy with early respiratory failure (HMERF) is a rare myopathy that affects respiratory muscles in the early course of the disease leading to respiratory insufficiency. It is caused by mutation in titin (TTN) gene. Case report: At the age of 29, our female patient presented with a slowly progressive proximal lower limb and axial muscle weakness and respiratory issues. Her late mother had similar problems, she died at a young age and was never properly diagnosed. Patient’s creatine kinase level was elevated up to three times above the upper limit of normal. Whole exome sequencing showed a pathogenic variant c.95372G>A in the TTN gene leading to the final diagnosis of HMERF. Cardiac examination was normal. Patient started to use a non-invasive nocturnal ventilation at age of 35. Conclusions: Our case is the first described case of HMERF in Serbian population. Multidisciplinary neurological and pulmonary approach is of great importance in HMERF and similar diseases. This case highlights the importance of considering early neuromuscular respiratory insufficiency as a distinctive syndrome leading to a challenging and broad differential diagnosis. © 2023, The Author(s).
