CASE REPORT: We present the clinical case of a female newborn with antecedents of oligoamnios and intrauterine growth retardation who presented a characteristic malformative syndrome, severe neurological impairment, anomalies of the limbs, pyloric stenosis, and renal and cardiac defects. Determination of cholesterol and its precursors by gas chromatography confirmed the clinical diagnosis of a severe form with exitus at six months of age.
