Preferred Label : Histidinuria due to a renal tubular defect;
Type : Phenotype or locus, molecular basis unknown;
Description : Sabater et al. (1976) described 2 brothers, aged 9 and 11 years, with mild mental
retardation and histidinuria despite normal blood levels. Histidine loading showed
impaired intestinal absorption. The inheritance is presumably autosomal recessive
because both parents showed intermediate intestinal absorption. Holmgren et al. (1974)
had reported 1 patient with renal histidinuria associated with myoclonic seizures.
Kamoun et al. (1981) likewise reported 1 patient with associated histidinuria and
myoclonic seizures. Nyhan and Hilton (1992) described a 7-year-old boy with histidinuria
without histidinemia. Low concentrations of histidine in plasma were consistent with
impaired intestinal and renal tubular absorption of histidine. The patient was developmentally
delayed and had some minor anomalies: bilateral nerve deafness of moderate severity;
protuberant large and somewhat simple oracles; very short thick fingers and toes with
hypoplasia of the toenails; and broad nasal bridge with long shallow philtrum and
thin upper lip. Roentgenograms showed that the shortness of the 5th digit resulted
from a short rounded middle phalanx that was abnormal in shape. All 5 patients who
have been reported have been male. *FIELD* RF 1. Holmgren, G.; Hambraeus, L.; Chateau,
