The c.760G>C (p.E254Q) alteration is located in exon 6 (coding exon 6) of the FAM86B1 gene. This alteration results from a G to C substitution at nucleotide position 760, causing the glutamic acid (E) at amino acid position 254 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
