Sindromul Kennedy (atrofie muscular\u0103 bulbar\u0103 \u0219i spinal\u0103 X-linkat\u0103) este o boal\u0103 neurodegenerativ\u0103 genetic\u0103 rar\u0103, determinat\u0103 de expansiunea anormal\u0103 a repet\u0103rilor CAG<\/strong> \u00een gena AR (Androgen Receptor)<\/strong>, situat\u0103 pe cromozomul X.<\/p>\n

Aceast\u0103 expansiune duce la acumularea unei proteine receptor androgenic anormale, cu efect toxic asupra neuronilor motori din trunchiul cerebral \u0219i m\u0103duva spin\u0103rii. Boala afecteaz\u0103 aproape exclusiv b\u0103rba\u021bii, \u00een timp ce femeile sunt de regul\u0103 purt\u0103toare asimptomatice sau prezint\u0103 manifest\u0103ri minime.<\/p>\n

Manifest\u0103rile clinice includ sl\u0103biciune muscular\u0103 progresiv\u0103, atrofie muscular\u0103, fascicula\u021bii, afectare bulbar\u0103 (dificult\u0103\u021bi de vorbire \u0219i degluti\u021bie), tremor \u0219i, frecvent, ginecomastie \u0219i tulbur\u0103ri endocrine asociate.<\/p>\n

Analiza expansiunii repetitive din gena AR este metoda standard pentru confirmarea diagnosticului de sindrom Kennedy.<\/p>\n
