The variant allele was found at a frequency of 0.322 in 152,022 control chromosomes in the GnomAD database, including 9,596 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.32 (9596 hom., cov: 32)
• Consequence: CALN1 NM_031468.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.0400

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.5).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.44 is higher than 0.05.
