The c.246G>T (p.L82F) alteration is located in exon 4 (coding exon 3) of the SLC28A2 gene. This alteration results from a G to T substitution at nucleotide position 246, causing the leucine (L) at amino acid position 82 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
