脊髓性肌萎縮伴進行性肌陣攣性癲癇(spinal muscular atrophy with progressive myoclonic epilepsy,SMA-PME),有時也稱Jankovic-Rivera綜合症(Jankovic–Rivera syndrome),是一種非常罕見的神經退行性疾病,症狀包括緩慢進行性肌肉萎縮,主要影響遠側肌肉,伴有失神經支配英語denervation肌陣攣發作[1]。科學文獻僅載有12個家族患有SMA-PME[2]

SMA-PME與ASAH1基因外顯子2錯義突變(c.125C→T)或刪除有關,為常染色體隱性遺傳[3]。SMA-PME與一種名為法伯脂肪肉芽腫病的溶酶體疾病密切相關[4]。與許多遺傳紊亂疾病一樣,SMA-PME尚無治癒方法。

美國研究者Joseph Jankovic和Victor M. Rivera在1979年首次描述了這種病症[5]

ASAH1基因

ASAH1基因編碼溶酶體中的酸性神經酰胺酶。溶酶體分解酸性神經酰胺酶,然後利用脂肪酸成分[6]產生髓磷脂。髓磷脂圍繞在機體神經周圍,有助於信號在神經細胞間的傳遞,並提高傳輸速率[7]。SMA-PME患者體內神經酰胺酶功能減弱三分之二[2]。酸性神經酰胺酶分解缺乏導致髓磷脂缺乏,進而導致神經細胞損傷。
