目的
2
探讨伴有酸中毒的家族性低钾型周期性瘫痪的诊断和治疗。
方法
2
分析先证者病史、临床表现、实验室检查和影像学特点,详细调查家系患病情况,应用二代测序技术检测低钾血症相关致病基因位点,对国内外相关文献进行归纳总结。
结果
2
明确诊断先证者为家族性低钾型周期性瘫痪,先证者的
SCN4A
基因有1个杂合突变,为c.2006G
>
A,导致氨基酸改变p.R669H。先证者的祖父、父亲和伯伯存在相同变异。
结论
2
伴酸中毒的家族性低钾型周期性瘫痪罕见,容易误诊为肾小管酸中毒,临床上要提高警惕。
SCN4A
基因c.2006G
>
A突变是该家系发病的分子基础。不同基因突变的临床表型存在差异,基因筛查有助诊断分型和治疗方案选择。
Objective
2
To investigate the diagnosis and treatment of familial hypokalemic periodic paralysis with acidosis.
Methods
2
The proband's medical history, clinical manifestations, laboratory examinations and imaging characteristics were retrospectively analyzed, and prevalence situation of family members was investigated in detail. Next generation sequencing technology was used to detect the pathogenic gene loci related to periodic paralysis, and the relevant literatures were summarized.
Results
2
The proband was definitely diagnosed as familial hypokalemic periodic paralysis. There was a heterozygous mutation in the
SCN4A
gene of the proband, which was c.2006G
>
A, resulting in amino acid changes R669H.The proband's grandfather, father and uncle shared the same variation.
Conclusions
2
Familial hypokalemic periodic paralysis with paroxysmal acidosis is rare, which is easily misdiagnosed as renal tubular acidosis. c 2006G
>
A mutation in
SCN4A
gene is the molecular basis of the disease in this family. The clinical phenotypes of different gene mutations are different, and gene screening is helpful for diagnosis and treatment.
