The c.564G>C (p.Q188H) alteration is located in exon 5 (coding exon 1) of the FAM110B gene. This alteration results from a G to C substitution at nucleotide position 564, causing the glutamine (Q) at amino acid position 188 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
