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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 27, 2021The c.86C>T (p.P29L) alteration is located in exon 2 (coding exon 1) of the CALN1 gene. This alteration results from a C to T substitution at nucleotide position 86, causing the proline (P) at amino acid position 29 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
