Genes affected
CAMKK2 (HGNC:1470): (calcium/calmodulin dependent protein kinase kinase 2) The product of this gene belongs to the Serine/Threonine protein kinase family, and to the Ca(2+)/calmodulin-dependent protein kinase subfamily. The major isoform of this gene plays a role in the calcium/calmodulin-dependent (CaM) kinase cascade by phosphorylating the downstream kinases CaMK1 and CaMK4. Protein products of this gene also phosphorylate AMP-activated protein kinase (AMPK). This gene has its strongest expression in the brain and influences signalling cascades involved with learning and memory, neuronal differentiation and migration, neurite outgrowth, and synapse formation. Alternative splicing results in multiple transcript variants encoding distinct isoforms. The identified isoforms differ in their ability to undergo autophosphorylation and to phosphorylate downstream kinases. [provided by RefSeq, Jul 2012]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.1240G>A (p.D414N) alteration is located in exon 13 (coding exon 12) of the CAMKK2 gene. This alteration results from a G to A substitution at nucleotide position 1240, causing the aspartic acid (D) at amino acid position 414 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
