W. Byerley et al., LINKAGE ANALYSIS BETWEEN SCHIZOPHRENIA AND INDEX SIMPLE-SEQUENCE REPEAT LOCI FOR CHROMOSOME-21, Human heredity, 45(1), 1995, pp. 49-52
Nine multiplex schizophrenia families were genotyped with seven highly
polymorphic microsatellite loci used in the construction of an index
map of chromosome 21. Assuming either autosomal dominant or recessive
transmission, evidence of linkage was not found. In addition, the nonp
arametric sib-pair test did not yield significant evidence of linkage.
