Gelsolin-related amyloidosis (AGel amyloidosis) is a rare autosomal dominant disorder, reported worldwide in kindreds carrying a G654A or G654T gelsolin gene mutation. The main clinical signs are cutis laxa, cranial and peripheral neuropathy, and corneal lattice dystrophy but heavy intermittent snoring also occurs. To evaluate whether sleep apnoea is present we performed nocturnal sleep recordings, cephalometric and spirometric analyses and multiple sleep latency tests (MSLT) in five snoring patients with a G654A gelsolin gene mutation. Four patients had obstructive sleep apnoea syndrome (OSAS) with redundant oropharyngeal and hypopharyngeal soft tissues, macroglossia and cranial neuromuscular dysfunction. The fifth patient had hypersomnia without obstructive sleep apnoea. Nasal continuous positive airway pressure (CPAP) was an effective treatment. This study presents the first evidence in favour of an association between AGel amyloidosis and OSAS, but further studies are needed to define the prevalence of OSAS and the pathogenetic roles of amyloid and variant gelsolin in its evolution.
