The c.521G>A (p.G174E) alteration is located in exon 5 (coding exon 5) of the LIX1 gene. This alteration results from a G to A substitution at nucleotide position 521, causing the glycine (G) at amino acid position 174 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
