Autosomal Dominant Obstructive Sleep Apnea Syndrome Due to the New Variant c.980_984dup in COL1A2: A Case Report

This case report describes a 72-year-old woman with obstructive sleep apnea syndrome (OSAS) linked to a novel genetic variant, c.980_984dup, in the COL1A2 gene, marking the first documented instance of hereditary OSAS due to this mutation. The patient, who had a history of insomnia and other medical issues such as joint hypermobility and hair loss, showed improvement with nocturnal active positive airway pressure treatment. Her son also developed OSAS, prompting genetic testing that identified the COL1A2 mutation. This finding suggests that OSAS can be hereditary and associated with connective tissue disorders, highlighting the importance of genetic testing in patients with a family history of OSAS.
