Sep 1, 2022 · Long-chain hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency and trifunctional protein (TFP) deficiency are caused by impairment of mitochondrial TFP. TFP has three enzymatic activities – long-chain enoyl-CoA hydratase, long-chain 3-hydroxyacyl-CoA dehydrogenase, and long-chain 3-ketoacyl-CoA thiolase.

Long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency is a rare condition that prevents the body from converting certain fats to energy, particularly during periods without food (fasting). Signs and symptoms of LCHAD deficiency typically appear during infancy or …

Episodes of LCHAD deficiency can be triggered by periods of fasting or by illnesses such as viral infections. Mutations in the HADHA gene lead to inadequate levels of an enzyme called long-chain 3-hydroxyacyl-coenzyme A (CoA) dehydrogenase, which is part of a protein complex known as mitochondrial trifunctional protein.

Deficiency of the mitochondrial trifunctional protein (TFP) and long-chain 3-Hydroxy Acyl-CoA dehydrogenase (LCHAD) impairs long-chain fatty acid oxidation and presents with hypoglycemia, cardiac, liver, eye, and muscle involvement. Without …

Long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency is a rare condition that prevents the body from converting certain fats to energy, particularly during periods without food (fasting).

长链3-羟酰基辅酶A脱氢酶(long chain 3-hydroxyacyl-CoA dehydrogenase，LCHAD)是 线粒体三功能蛋白 (mitochondrial trifunctional protein，MTP)的组成之一，特异性代谢C12～Cl6链长的脂肪酸复合物。LCHAD缺陷导致体内长链脂肪酸代谢障碍，在机体长期饥饿状态需由脂肪酸产能的情 况 …

长链3-羟酰基辅酶A脱氢酶缺乏症（long chain 3-hydroxyacyl-CoA dehydrogenase deficiency, LCHADD），是一种罕见的遗传代谢病，属常染色体隐性遗传。 患者症状表现复杂，可在新生儿到成年发病，轻重不同，常见无力、喂养困难、昏迷、肌痛等症状，严重者出现肝病、心肌病，甚至猝死。 2018年5月11日，该疾病被列入国家卫生健康委员会等5部门联合制定的《第一批罕见病目录》。 由于编码长链3-羟酰基辅酶A脱氢酶的HADHA基因突变,导致线粒体长链脂肪代谢障 …

长链 3-羟酰基辅酶 A 脱氢酶（LCHAD）是线粒体脂肪酸 β 氧化中重要的多酶复合体 MTP 的组成之一。 编码 LCHAD 的基因突变导致该酶形成障碍，导致 MTP 缺乏或功能障碍，进而导致线粒体中脂肪氧化缺陷，引起一系列脏器功能异常和代谢异常。 长链3-羟酰基辅酶A脱氢酶缺乏症的常见人群是什么？ 该病最常见于新生儿、幼儿及儿童发病，少数亦有青少年或成人发病。 长链3-羟酰基辅酶A脱氢酶缺乏症的主要表现是什么？ 该病根据突变类型不同、酶活性损害的程度不同及受 …

LCHAD is a type of fatty acid oxidation disorder. People with LCHAD have problems breaking down fat into energy for the body. What Causes LCHAD? Enzymes help start chemical reactions in the body. LCHAD happens when an enzyme called “long chain 3-hydroxyacyl-CoA dehydrogenase” is either missing or not working.
