The KAL1 gene is a human gene which is located on the X chromosome at Xp22.3 and is affected in some individuals with Kallmann syndrome. This gene codes for a protein named anosmin-1 which is responsible for migration of certain nerve cell precursors during embryogenesis. Deletion or mutation of this gene results in loss of the functional protein and affects the proper development of the olfactory system.
