The c.927A>C (p.Q309H) alteration is located in exon 9 (coding exon 8) of the CAB39L gene. This alteration results from a A to C substitution at nucleotide position 927, causing the glutamine (Q) at amino acid position 309 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
