Sep 16, 2021

The c.668A>G (p.H223R) alteration is located in exon 2 (coding exon 1) of the FAM110A gene. This alteration results from a A to G substitution at nucleotide position 668, causing the histidine (H) at amino acid position 223 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
