Genes affected

UNC79 (HGNC:19966): (unc-79 homolog, NALCN channel complex subunit) The NALCN channel is responsible for Na(+) leak currents. The protein encoded by this gene, along with UNC80, is an accessory subunit of the NALCN channel that contributes to the Ca(2+) sensitivity of the channel. [provided by RefSeq, Sep 2016]

The c.43G>A (p.D15N) alteration is located in exon 4 (coding exon 1) of the UNC79 gene. This alteration results from a G to A substitution at nucleotide position 43, causing the aspartic acid (D) at amino acid position 15 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
