The c.248G>A (p.R83Q) alteration is located in exon 5 (coding exon 3) of the SLC28A1 gene. This alteration results from a G to A substitution at nucleotide position 248, causing the arginine (R) at amino acid position 83 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
