The c.1267A>T (p.I423F) alteration is located in exon 5 (coding exon 5) of the SLC15A3 gene. This alteration results from a A to T substitution at nucleotide position 1267, causing the isoleucine (I) at amino acid position 423 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
