Remarks |
Clinically affected; pregnancy complicated by pregnancy induced hypertension with HELLP syndrome; subject born at 26 6/7 weeks gestation due to fetal distress; birth weight 709 grams; respiratory distress syndrome; metabolic acidosis; hyponatremia; hypochloremia; hypophosphatemia; anemia; feeding intolerance with ileus; hyperbilirubinemia; neutropenia; single umbilical artery; severe hypotension; myocardial dysfunction with poor contractility; renal dysfunction with elevated creatinine; renal ultrasound showed nonspecific bilateral renal cortical disease; subject died in first month of life; total carnitine was 110 micromoles per liter; free carnitine was 39.5 micromoles per liter; acyl to free carnitine ratio was 1.8; acyl carnitine profile showed marked elevation in the C16 and C18 hydroxy acyl carnitines; donor subject is homozygous for a G>A transition at nucleotide 182 in exon 4 of the HADHB gene [182G>A] resulting in a substitution of histidine for arginine at codon 28 [Arg28His (R28H)]. The donor is also homozygous for a presumed polymorphism: 1050A>G which does not change the codon for glutamine317. |
