The c.399G>A (p.M133I) alteration is located in exon 5 (coding exon 3) of the SLC14A1 gene. This alteration results from a G to A substitution at nucleotide position 399, causing the methionine (M) at amino acid position 133 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
