Genes affected

CALB1 (HGNC:1434): (calbindin 1) The protein encoded by this gene is a member of the calcium-binding protein superfamily that includes calmodulin and troponin C. Originally described as a 27 kDa protein, it is now known to be a 28 kDa protein. It contains four active calcium-binding domains, and has two modified domains that are thought to have lost their calcium binding capability. This protein is thought to buffer entry of calcium upon stimulation of glutamate receptors. Depletion of this protein was noted in patients with Huntington disease. [provided by RefSeq, Jan 2015]

Dec 09, 2024

The c.113A>G (p.N38S) alteration is located in exon 2 (coding exon 2) of the CALB1 gene. This alteration results from a A to G substitution at nucleotide position 113, causing the asparagine (N) at amino acid position 38 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
