The c.386G>C (p.R129P) alteration is located in exon 2 (coding exon 1) of the FAM110A gene. This alteration results from a G to C substitution at nucleotide position 386, causing the arginine (R) at amino acid position 129 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
