Genes affected

TPCN1 (HGNC:18182): (two pore segment channel 1) Voltage-gated Ca(2+) and Na+ channels have 4 homologous domains, each containing 6 transmembrane segments, S1 to S6. TPCN1 is similar to these channels, but it has only 2 domains containing S1 to S6 (Ishibashi et al., 2000 [PubMed 10753632]).[supplied by OMIM, Mar 2008]

The c.167C>T (p.T56I) alteration is located in exon 3 (coding exon 2) of the TPCN1 gene. This alteration results from a C to T substitution at nucleotide position 167, causing the threonine (T) at amino acid position 56 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
