Preferred Label : Renal hypodysplasia/aplasia 1;
Symbol : RHDA1;
CISMeF acronym : HRA; RHDA1;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Renal aplasia; Renal agenesis; Hereditary renal aplasia; HRA; Renal adysplasia;
Description : Bilateral renal agenesis (BRA) belongs to a group of perinatally lethal renal diseases,
including severe bilateral renal dysplasia, unilateral renal agenesis with contralateral
dysplasia (URA/RD) and severe obstructive uropathy. The estimated incidence of perinatally
lethal renal disease is 1 in 4,000 to 1 in 6,400 births with an apparent male preponderance.
Families have been documented in which bilateral renal agenesis or aplasia coexists
with unilateral renal aplasia, renal dysplasia, or renal aplasia with renal dysplasia,
suggesting that these conditions belong to a pathogenic continuum or phenotypic spectrum
(Joss et al., 2003). Buchta et al. (1973) coined the term hereditary renal 'adysplasia,'
which combines the terms aplasia and dysplasia. See also 193000 for a discussion of
congenital anomalies of the kidney and urinary tract (CAKUT), which shows some phenotypic
overlap with the disorder described here.;
