The c.358G>C (p.E120Q) alteration is located in exon 1 (coding exon 1) of the FAM47C gene. This alteration results from a G to C substitution at nucleotide position 358, causing the glutamic acid (E) at amino acid position 120 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
