The c.329A>T (p.N110I) alteration is located in exon 5 (coding exon 4) of the SLC37A3 gene. This alteration results from a A to T substitution at nucleotide position 329, causing the asparagine (N) at amino acid position 110 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
