The c.673C>A (p.P225T) alteration is located in exon 2 (coding exon 2) of the FAM120AOS gene. This alteration results from a C to A substitution at nucleotide position 673, causing the proline (P) at amino acid position 225 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
