The c.331A>G (p.T111A) alteration is located in exon 4 (coding exon 3) of the CAB39L gene. This alteration results from a A to G substitution at nucleotide position 331, causing the threonine (T) at amino acid position 111 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
