The c.352C>G (p.Q118E) alteration is located in exon 1 (coding exon 1) of the FAM155A gene. This alteration results from a C to G substitution at nucleotide position 352, causing the glutamine (Q) at amino acid position 118 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
