Global Lactase persistence Association Database
Lactase persistence (LP) is the ability of adult humans to digest the milk sugar lactose. LP is a dominant Mendelian trait that has been a subject of extensive genetic, medical, and evolutionary research.
This is an online database resource presenting the full LP phenotypic and LP-associated allele frequency data, including worldwide interpolated LP frequencies and genotype-phenotype correlation maps.
We encourage researchers to send us new LP phenotype / genotype data to Professor Dallas Swallow in an Excel format using headers identical to those in the tables linked below.
Please make sure that the submitted phenotype data conform to the following criteria:
-Known ethnicity and sampling location
-No hospital patients or individuals self reporting with gut problems
