The c.1192G>C (p.E398Q) alteration is located in exon 8 (coding exon 8) of the SLC35F1 gene. This alteration results from a G to C substitution at nucleotide position 1192, causing the glutamic acid (E) at amino acid position 398 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
