An example of genetic inheritance of KN.

Malian family shows inheritance of McC^a with amino acid 1590K, McC^b with 1590E, Sl^a with 1601R, and Vil with 1601G. The father passes the CR1*1 allele bearing McC^b(E)/Vil (G) to both sons. The mother passes the McC^a(K)/Vil (G) haplotype to son 990052 and the McC^a(K)/Sl^a (R) haplotype to son 990026.
