Mineralocorticoid receptor mutations and a severe recessive pseudohypoaldosteronism type 1.
Pseudohypoaldosteronism type 1 (PHA1) is a rare genetic disease of mineralocorticoid resistance characterized by salt wasting and failure to thrive in infancy. Here we describe the first case of a newborn with severe recessive PHA1 caused by two heterozygous mutations in NR3C2, gene coding for the mineralocorticoid receptor (MR). Independent segregation of the mutations occurred in the family, ...
متن کاملExclusion of the locus for autosomal recessive pseudohypoaldosteronism type 1 from the mineralocorticoid receptor gene region on human chromosome 4q by linkage analysis.
Pseudohypoaldosteronism type 1 (PHA1) is an uncommon inherited disorder characterized by salt-wasting in infancy arising from target organ unresponsiveness to mineralocorticoids. Clinical expression of the disease varies from severely affected infants who may die to apparently asymptomatic individuals. Inheritance is Mendelian and may be either autosomal dominant or autosomal recessive. A defec...
متن کاملPseudohypoaldosteronism in a newborn male with functional polymorphisms in the mineralocorticoid receptor genes
Hyponatremia and hyperkalemia in infancy can be attributed to various causes, originating from a variety of renal and genetic disorders. Pseudohypoaldosteronism type 1 (PHA1) is one of these disorders, causing mineralocorticoid resistance that results in urinary salt wasting, failure to thrive, metabolic acidosis, and dehydration. PHA1 is heterogeneous in etiology. Inactivating mutations in the...
متن کاملA case of pseudohypoaldosteronism type 1 with a mutation in the mineralocorticoid receptor gene
Pseudohypoaldosteronism type 1 (PHA1) is a rare form of mineralocorticoid resistance characterized in newborns by salt wasting with dehydration, hyperkalemia and failure to thrive. This disease is heterogeneous in etiology and includes autosomal dominant PHA1 owing to mutations of the NR3C2 gene encoding the mineralocorticoid receptor, autosomal recessive PHA1 due to mutations of the epithelial...
متن کاملPhenotypic variation of autosomal recessive pseudohypoaldosteronism type I: a case in point
KEY CLINICAL MASSAGE We present a 27-month-old male infant with pseudohypoaldosteronism, with two novel α-subunits, epithelial sodium channel (ENaC) mutations. Despite the presence of the ENaC in the lungs, kidneys, and exocrine glands, he continues to only have renal and exocrine involvement, stressing differential effects of the mutation in each organ.
