Transient infantile hypertriglyceridemia (HTGTI) is a rare autosomal recessive inherited disease caused by inactivating mutations in the glycerol-3-phosphate dehydrogenase 1 gene. To date, only a few patients have been reported worldwide. The symptoms of the affected individuals present a certain degree of transient hypertriglyceridemia, hepatomegaly, elevated liver enzymes, persistent fatty liver and hepatic fibrosis in early infancy. However, the clinical characteristics and pathogenesis of this disease are remain unclear.
A one month and twenty-five days old girl was admitted to hospital because of persisted jaundice and hepatomegaly for fifty days.
The girl was diagnosed with HTGTI coincident with a noval mutation in glycerol-3-phosphate dehydrogenase 1.
She was advised to take low-fat diet and supplement of medium-chain fatty acids.
Her jaundice was gradually normal at the age of 4 months without any treatment, and hypertriglyceridemia were normal at the age of 13 months, but still had elevated transaminases and hepatic steatosis.
Jaundice may be a novel phenotype in HTGTI. The report contributes to the expansion of HTGTI's gene mutation spectrum and its clinical manifestations.
短暂性婴儿期高甘油三酯血症(HTGTI)是一种罕见的常染色体隐性遗传性疾病,由甘油-3-磷酸脱氢酶 1 基因失活突变引起。迄今为止,全世界仅报道了少数几例患者。受影响个体的症状表现出一定程度的短暂性高甘油三酯血症、肝肿大、肝酶升高、早期持续性脂肪肝和肝纤维化。然而,该疾病的临床特征和发病机制仍不清楚。
一名 1 个月零 25 天的女婴因黄疸和肝肿大持续 50 天而入院。
该女孩被诊断为 HTGTI,同时伴有甘油-3-磷酸脱氢酶 1 的新突变。
建议她采用低脂饮食和中链脂肪酸补充。
她的黄疸在 4 个月大时逐渐恢复正常,无需任何治疗,高甘油三酯血症在 13 个月大时恢复正常,但仍存在转氨酶升高和肝脂肪变性。
黄疸可能是 HTGTI 的一种新表型。该报告有助于扩大 HTGTI 的基因突变谱及其临床表现。
