The c.593G>T (p.R198L) alteration is located in exon 2 (coding exon 2) of the FAM120AOS gene. This alteration results from a G to T substitution at nucleotide position 593, causing the arginine (R) at amino acid position 198 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
