RT Journal Article SR Electronic T1 New allele at cholinesterase locus 1. JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 38 OP 42 DO 10.1136/jmg.13.1.38 VO 13 IS 1 A1 P J Garry A1 A A Dietz A1 T Lubrano A1 P C Ford A1 K James A1 H M Rubinstein YR 1976 UL http://jmg.bmj.com/content/13/1/38.abstract AB A family (H-J pedigree) segregating for the A and F alleles at cholinesterase locus 1 is described. Apparent anomalous results led to the recognition of a new allele (E1j) also segregating in the family. The data are consistent with the hypothesis that the the E1j causes reduction of 'usual' (E1u) molecules by about 66%. Whether this is because of retarded synthesis or accelerated degradation of serum cholinesterase remains to be determined.
