Genes affected

SERGEF (HGNC:17499): (secretion regulating guanine nucleotide exchange factor) Predicted to enable guanyl-nucleotide exchange factor activity. Involved in negative regulation of protein secretion. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

SERGEF links:

KCNC1 (HGNC:6233): (potassium voltage-gated channel subfamily C member 1) This gene encodes a member of a family of integral membrane proteins that mediate the voltage-dependent potassium ion permeability of excitable membranes. Alternative splicing is thought to result in two transcript variants encoding isoforms that differ at their C-termini. These isoforms have had conflicting names in the literature: the longer isoform has been called both "b" and "alpha", while the shorter isoform has been called both "a" and "beta" (PMIDs 1432046, 12091563).

The c.1185C>A (p.H395Q) alteration is located in exon 11 (coding exon 11) of the SERGEF gene. This alteration results from a C to A substitution at nucleotide position 1185, causing the histidine (H) at amino acid position 395 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
