The c.814C>T (p.R272C) alteration is located in exon 8 (coding exon 7) of the CSNK1G2 gene. This alteration results from a C to T substitution at nucleotide position 814, causing the arginine (R) at amino acid position 272 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
