The c.465C>A (p.H155Q) alteration is located in exon 5 (coding exon 1) of the FAM110B gene. This alteration results from a C to A substitution at nucleotide position 465, causing the histidine (H) at amino acid position 155 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
