The c.1589G>A (p.G530E) alteration is located in exon 16 (coding exon 13) of the TMCO4 gene. This alteration results from a G to A substitution at nucleotide position 1589, causing the glycine (G) at amino acid position 530 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
