The c.332C>G (p.A111G) alteration is located in exon 5 (coding exon 5) of the U2AF1L4 gene. This alteration results from a C to G substitution at nucleotide position 332, causing the alanine (A) at amino acid position 111 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
