Abstract

The apo C-II gene from a patient with apo C-II deficiency has been sequenced after amplification by the polymerase chain reaction (PCR). The sequence analysis revealed a substitution of adenosine for cytosine at position 3, 002 in exon 3, leading to the introduction of a premature stop codon (TAA) at a position corresponding to aminoacid 37 of mature apo C-II. This mutation creates a new Rsa I restriction enzyme site in the apo C-II gene. Amplification of DNA from family members by PCR and digestion with Rsa I established that the patient is a true homozygote for this mutation. The same nucleotide has been substituted for the mutation apo C-IIPadova and apo C-IIBari previously described in two kindreds from Italy. From these data we speculate that base pair 3, 002 in the apo C-II gene may represent a hot spot for mutation.
