Autozomálně recesivní
Caused by changes in both copies of TOR1AIP1, which encodes LAP1, a protein of the inner nuclear membrane. Complete loss causes a severe early-onset multisystem disorder, while milder changes can cause a muscle-predominant form.
Příznaky a projevy
Severe forms present in infancy with growth failure, cataracts, hearing loss, heart problems and premature-ageing features. Milder forms cause progressive limb-girdle muscle weakness, joint contractures and cardiomyopathy.
Co se diagnózou změní
Regular heart, eye and hearing review, with physiotherapy and orthopaedic care. Carrier testing of relatives and genetic counselling are available.
