Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1750G>A (p.G584S) alteration is located in exon 5 (coding exon 4) of the SLC7A4 gene. This alteration results from a G to A substitution at nucleotide position 1750, causing the glycine (G) at amino acid position 584 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
