>3 unrelated cases: Congenital lactase deficiency is frequent in Finland due to a high carrier status of an LCT variant (PMID:16400612 report multiple Finnish cases of the recessive disorder). More recent papers describe LCT variants in patients with the disorder outside of Finland: PMID:19161632 (2009): Turkish, Italian and Finnish. Uchida (2012): Japanese. PMID:26215149 (2015): Turkish.
