The c.391C>T (p.L131F) alteration is located in exon 6 (coding exon 4) of the SLC28A1 gene. This alteration results from a C to T substitution at nucleotide position 391, causing the leucine (L) at amino acid position 131 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
