Genes affected

CAMKK1 (HGNC:1469): (calcium/calmodulin dependent protein kinase kinase 1) The product of this gene belongs to the Serine/Threonine protein kinase family, and to the Ca(2+)/calmodulin-dependent protein kinase subfamily. This protein plays a role in the calcium/calmodulin-dependent (CaM) kinase cascade. Three transcript variants encoding two distinct isoforms have been identified for this gene.

Apr 12, 2024

The c.758G>A (p.R253H) alteration is located in exon 9 (coding exon 8) of the CAMKK1 gene. This alteration results from a G to A substitution at nucleotide position 758, causing the arginine (R) at amino acid position 253 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
