Abstract

CONTEXT: Congenital lipoid adrenal hyperplasia (CLAH), caused by mutations in steroidogenic acute regulatory protein (StAR), is most frequent in Japanese and Palestinians. We report eight Palestinians from four unrelated families with CLAH. OBJECTIVE: The objective of the study was to identify the mutation(s) in StAR, correlate genotype with phenotype, and determine whether the common mutation represents a founder mutation. PATIENTS AND SETTING: Clinical, histopathological, and molecular genetic characterization was performed in these eight patients. RESULTS: All affected individuals (three XY, five XX) presented neonatally with undetectable adrenocortical hormones and are responding to replacement therapy. Only two sisters had neurodevelopmental deficits. Histopathological findings of excised XY gonads included accumulation of fat in Leydig cells. Significantly, already at 1 yr of age, positive placental alkaline phosphatase and octamer binding transcription factor staining indicated neoplastic potential. Sequence analysis of StAR revealed homozygosity for c.201_202delCT mutation in all eight cases, causing premature termination of the StAR protein. This mutation was confirmed to be a founder mutation using both an intragenic microsatellite and several single nucleotide polymorphism markers. Screening of 100 normal Jerusalem Palestinians detected no carriers of this mutation. CONCLUSION: CLAH is rare in the general Palestinian population. In most Palestinian cases, a founder c.201_202delCT mutation in StAR is the cause. The observed early neonatal presentation may reflect the major StAR protein truncation caused by this mutation. A crucial role for StAR in the central nervous system was not supported with normal neurological examinations in six of eight cases. Finally, we advocate early gonadectomy in XY CLAH cases, given the early onset of neoplastic changes observed histologically.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
