  • Title: A homozygous deletion/insertion mutation in the protein C (PROC) gene causing neonatal Purpura fulminans: prenatal diagnosis in an at-risk pregnancy.
    Author: Millar DS, Allgrove J, Rodeck C, Kakkar VV, Cooper DN.
    Journal: Blood Coagul Fibrinolysis; 1994 Aug; 5(4):647-9. PubMed ID: 7841323.
    Abstract:
    A novel homozygous mutation in the protein C (PROC) gene was detected in an individual with severe type I protein C deficiency who presented with neonatal Purpura fulminans. The deletion/insertion mutation found [3351del4, 3350insA] resulted in an Asn102-->Lys substitution and the removal of codon Gly103. First trimester prenatal diagnosis was performed in a subsequent pregnancy by chorionic villus sampling and PCR/direct sequencing; the foetus was shown to be heterozygous for the lesion. This diagnosis was confirmed phenotypically after the birth of a clinically healthy child.
