The c.472G>A (p.A158T) alteration is located in exon 4 (coding exon 4) of the KLHL18 gene. This alteration results from a G to A substitution at nucleotide position 472, causing the alanine (A) at amino acid position 158 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
