The c.2471C>G (p.T824R) alteration is located in exon 21 (coding exon 20) of the CATSPERB gene. This alteration results from a C to G substitution at nucleotide position 2471, causing the threonine (T) at amino acid position 824 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
