The c.377G>T (p.R126L) alteration is located in exon 5 (coding exon 3) of the FAM193A gene. This alteration results from a G to T substitution at nucleotide position 377, causing the arginine (R) at amino acid position 126 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
