The c.709G>T (p.A237S) alteration is located in exon 7 (coding exon 6) of the CSNK1G2 gene. This alteration results from a G to T substitution at nucleotide position 709, causing the alanine (A) at amino acid position 237 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
