The c.427G>A (p.E143K) alteration is located in exon 3 (coding exon 3) of the UMODL1 gene. This alteration results from a G to A substitution at nucleotide position 427, causing the glutamic acid (E) at amino acid position 143 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
