The c.601C>G (p.Q201E) alteration is located in exon 8 (coding exon 6) of the FAM126B gene. This alteration results from a C to G substitution at nucleotide position 601, causing the glutamine (Q) at amino acid position 201 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
