The c.1797G>T (p.Q599H) alteration is located in exon 3 (coding exon 3) of the CHADL gene. This alteration results from a G to T substitution at nucleotide position 1797, causing the glutamine (Q) at amino acid position 599 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
