Kenny-Caffey syndrome type 2 (KCS 2) is an extremely rare autosomal dominant genetic disorder characterized by proportionate short stature, hypoparathyroidism, skeletal dysplasia and facial deformities. It is caused by variants in FAM111A gene. The clinical manifestations of KCS2 are atypical and diverse. We present two cases with KCS 2 with short stature, skeletal deformities and eye abnormalities confirmed by genetic analysis. The first patient came to our hospital ...

Background: X-linked adrenoleukodystrophy (X-ALD) is caused by a defect in the gene ABCD1, which maps to Xq28 and codes for a peroxisomal membrane protein that is a member of the ATP-binding cassette transporter superfamily. This disease characterized by progressive neurologic dysfunction, occasionally associated with adrenal insufficiency.Objective and hypotheses: To identify mutations of gene ABCD1 in Vietnamese patients with X-ALD.</...

Background: Neonatal diabetes mellitus (NDM) is a rare (1:300 000–400 000 newborns) but potentially devastating metabolic disorder characterized by hyperglycemia combined with low levels of insulin. Two main groups have been recognized on clinical grounds, transient NDM (TNDM) and permanent NDM (PNDM).Objective and hypotheses: To describe clinical features and laboratory manifestations of patient with NDM and evaluate outcome of management.<p cl...

Background: Neonatal diabetes is a rare disorder with an incidence of between 1 in 215 000–500 000 live births with approximately 50% having permanent neonatal diabetes (PNDM). Insulin gene (INS) mutations have recently been described as a cause of PNDM.Objective and hypotheses: To describe clinical features and laboratory manifestations of patient with PNDM due to INS gene mutation and evaluate outcome of management....

Background: Hyperinsulinemic hypoglycemia (HH) is a consequence of unregulated insulin secretion by pancreatic β-cells. Congenital HH is caused by mutations in genes involved in regulation of insulin secretion (ABCC8, KCNJ11, GLUD1, CGK, HADH, SLC16A1, HNF4A and UCP2). Severe forms of congenital HH are caused by inactivating mutations in ABCC8 and KCNJ11, which encode the two components of th...

Background: Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare and life-threatening primary immunodeficiency characterized by widespread autoimmunity. Mutations in the FOXP3 gene have been identified as the cause for IPEX syndrome.Objective and hypotheses: To describe clinical characteristics and genetic finding in the first Vietnamese patient with mutation of FOXP3 gene.Meth...

Background: Neonatal diabetes may be defined as hyperglycemia diagnosed within the first 6 months of life which is permanent neonatal diabetes or transient neonatal diabetes. They can result from some gene mutations such as KCNJ11, ABCC8, INS, GCK, … In there, the most common cause of neonatal diabetes mellitus is associated with activating mutations in the KCNJ11 gene, which encodes Kir6.2-a subunit of the ATP-sensitive potassium channel (KATP) of the β cell and AB...

Congenital hyperinsulinism (CHI) is a rare hereditary condition that causes excessive insulin production in the clinical picture of severe hypoglycemia. Patients with CHI frequently have mutations in the ABCC8 and KCNJ11 genes, which code for KATP channels in pancreatic beta cells. We present a case of partial diazoxide responsiveness caused by a heterozygous ABCC8 mutation in a child with moderate CHI. A four-month-old term baby with a ...
