The c.577G>T (p.G193C) alteration is located in exon 4 (coding exon 4) of the FAM178B gene. This alteration results from a G to T substitution at nucleotide position 577, causing the glycine (G) at amino acid position 193 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
