In a Japanese paternity test, an alleged father was excluded only by reverse homozygosity of esterase D (ESD) phenotypes (mother, ESD 1; child, ESD 1; alleged father, ESD 2) out of 43 classical and DNA markers investigated. To solve the aberrant inheritance of the ESD phenotypes observed between them, fragments for all eight coding exons amplified by polymerase chain reaction (PCR) were subjected to DNA analysis. The child and alleged father shared a null allele, originating from ESD*1. It was characterized by having TGA for the stop codon instead of TCA for serine at codon 63. Thus, the sharing of a rare null gene, ESD*Q0yonago, increased the probability of paternity. [Copyright &y& Elsevier]
