Gene Gene information from NCBI Gene database.
Entrez ID 149461
Gene name Claudin 19
Gene symbol CLDN19
Synonyms (NCBI Gene)
HOMG5
Chromosome 1
Chromosome location 1p34.2
Summary The product of this gene belongs to the claudin family. It plays a major role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity. Defects in this gene are the cause of hypomagnesemia rena
