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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.652C>T (p.R218C) alteration is located in exon 12 (coding exon 9) of the UNC79 gene. This alteration results from a C to T substitution at nucleotide position 652, causing the arginine (R) at amino acid position 218 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
