Gene: [AMY/01p21] amylase; (AMY1A AMY1B AMY1C AMY2A AMY2B AMYP1)

GEN

There are two main haplotypes in population; the short one is 100 kb in length (2B-2A-1C), and the long one is 300 kb or more (depending on the number of copies of the [1A-1B-P1] region."

FUN

The alpha amylase catalyzes the endohydrolysis of 1,4-alpha-D-glucoside bounds in polysaccharides containing three or more 1,4-alpha-D-glucoside residues."

MAF

Groot et al. reported the physical map of a complex locus containing all coding genes of the salivary and pancreatic amylases (Groot-1989). In particular, a 300-kb DNA fragment contains these elements in the following order: <<-2B-2A-[1A-1B-P1-1A-1B-P1]-1C->>. The area indicated in brackets is a direct repeat about 200 kb in length."
