What is lactase persistence? (genetrack.ie)
Lactase persistence is the ability to produce the lactase enzyme throughout one's life. (genetrack.ie)
Genetic variation plays a crucial role in predicting lactose intolerance and lactase persistence. (genetrack.ie)
How are lactose intolerance and lactase persistence inherited? (genetrack.ie)
Lactose intolerance and lactase persistence are inherited traits influenced by the LCT (lactase) and MCM6 (regulatory protein) genes, both located on chromosome two, one of the autosomal chromosomes. (genetrack.ie)
Inheriting two copies of the variant MCM6 gene leads to lactase persistence and the ability to pass on this lactase persistence trait to the next generation. (genetrack.ie)
Individuals with one copy of the normal MCM6 gene and one copy of the variant MCM6 gene typically exhibit lactase persistence, although some lactose sensitivity may still be possible. (genetrack.ie)
This pattern of inheritance is known as autosomal dominant since only one variant gene copy is necessary for lactase persistence. (genetrack.ie)
