NCIt definition : Human CGNL1 wild-type allele is located in the vicinity of 15q21.3 and is approximately
174 kb in length. This allele, which encodes cingulin-like protein 1, is involved
in the formation of tight junctions. A chromosomal inversion that positions the CGNL1
gene promoter into a position close to the CYP19A1 gene coding region is associated
with aromatase excess syndrome.;
