The c.1238G>A (p.R413Q) alteration is located in exon 12 (coding exon 11) of the CSNK1G2 gene. This alteration results from a G to A substitution at nucleotide position 1238, causing the arginine (R) at amino acid position 413 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
