Description

CALM2 NM_001743.5 exon 3 p.Thr35Ile (c.104C>T): This variant has not been reported in the literature but is present in 0.009% (1/10076) of Ashkenazi Jewish alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/2-47389732-G-A). Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain.
