The c.1723G>A (p.V575I) alteration is located in exon 12 (coding exon 10) of the SLC7A1 gene. This alteration results from a G to A substitution at nucleotide position 1723, causing the valine (V) at amino acid position 575 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
