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.1169G>A (p.G390D) alteration is located in exon 11 (coding exon 11) of the SERGEF gene. This alteration results from a G to A substitution at nucleotide position 1169, causing the glycine (G) at amino acid position 390 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
