linkage unit

a unit of ‘distance’ between genes along a chromosome. The number of map units is directly correlated with the amount of RECOMBINATION between loci; 1% recombination is equal to 1 map unit. See CROSS-OVER VALUE, GENETIC LINKAGE.

At present, there are two dedicated health record linkage units in Australia:
We also acknowledge the foresight of Dr Geoff Clarke, Dr John Weekes, and Dr Karl Donovan who (in conjunction with GJD and KYL) established the ICU database, Alexie Stoney (Western Australian Data Linkage unit) who performed the linkage of patient records and hazel Cowie (ICU clerical assistant) for assistance with ICu coding query resolution.
