The c.529G>A (p.E177K) alteration is located in exon 1 (coding exon 1) of the C1GALT1C1L gene. This alteration results from a G to A substitution at nucleotide position 529, causing the glutamic acid (E) at amino acid position 177 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
