Genes affected

CALN1 (HGNC:13248): (calneuron 1) This gene encodes a protein with high similarity to the calcium-binding proteins of the calmodulin family. The encoded protein contains two EF-hand domains and potential calcium-binding sites. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

The c.418A>C (p.M140L) alteration is located in exon 5 (coding exon 4) of the CALN1 gene. This alteration results from a A to C substitution at nucleotide position 418, causing the methionine (M) at amino acid position 140 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
