The c.1778C>G (p.P593R) alteration is located in exon 3 (coding exon 3) of the CHADL gene. This alteration results from a C to G substitution at nucleotide position 1778, causing the proline (P) at amino acid position 593 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
