Genes affected

PANX1 (HGNC:8599): (pannexin 1) The protein encoded by this gene belongs to the innexin family. Innexin family members are the structural components of gap junctions. This protein and pannexin 2 are abundantly expressed in central nerve system (CNS) and are coexpressed in various neuronal populations. Studies in Xenopus oocytes suggest that this protein alone and in combination with pannexin 2 may form cell type-specific gap junctions with distinct properties. [provided by RefSeq, Jul 2008]

Dec 26, 2023

The c.300C>A (p.N100K) alteration is located in exon 2 (coding exon 2) of the PANX1 gene. This alteration results from a C to A substitution at nucleotide position 300, causing the asparagine (N) at amino acid position 100 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
