Heterozygous missense variants in have been recently identified in 13 patients from 6 families with congenital myopathy with tremor. All the patients had mild skeletal myopathy invariably associated with a distinctive myogenic tremor and hypotonia with gradual clinical improvement. However, no phenotypic description has been reported for the neonatal respiratory impairment that patients may suffer.
We report 3 new patients from 2 independent families with congenital myopathy with tremor.
Tremors and respiratory distress associated with stridor should raise the diagnosis of congenital myopathy with tremors linked to -dominant variants in children with neonatal hypotonia.
Neonatal severe respiratory impairment requiring intensive noninvasive ventilation because of stridor is described in 2 patients. Stridor was previously reported in one other case and is part of the clinical features.
最近在来自6个患有先天性肌病伴震颤的家族的13名患者中鉴定出了 中的杂合错义变体。所有患者均患有轻度骨骼肌病，始终伴有独特的肌源性震颤和肌张力减退，临床症状逐渐改善。然而，尚未有关于患者可能出现的新生儿呼吸功能损害的表型描述。
我们报告了来自2个独立家族的3名患有先天性肌病伴震颤的新患者。
震颤和与喘鸣相关的呼吸窘迫应提高对新生儿肌张力减退儿童中与 -显性变体相关的先天性肌病伴震颤的诊断。
2例患者出现了因喘鸣而需要强化无创通气的新生儿严重呼吸功能损害。喘鸣先前在另一例病例中已有报道，是临床特征的一部分。
