The c.601G>A (p.A201T) alteration is located in exon 7 (coding exon 5) of the SLC28A1 gene. This alteration results from a G to A substitution at nucleotide position 601, causing the alanine (A) at amino acid position 201 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
