The c.579G>T (p.W193C) alteration is located in exon 5 (coding exon 5) of the FAM173B gene. This alteration results from a G to T substitution at nucleotide position 579, causing the tryptophan (W) 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. -
