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]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 16, 2022 | The c.1028C>T (p.T343I) alteration is located in exon 14 (coding exon 11) of the UNC79 gene. This alteration results from a C to T substitution at nucleotide position 1028, causing the threonine (T) at amino acid position 343 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
