The c.2827C>T (p.R943C) alteration is located in exon 24 (coding exon 23) of the CATSPERB gene. This alteration results from a C to T substitution at nucleotide position 2827, causing the arginine (R) at amino acid position 943 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
