The c.1753C>T (p.R585W) alteration is located in exon 6 (coding exon 6) of the FAM161B gene. This alteration results from a C to T substitution at nucleotide position 1753, causing the arginine (R) at amino acid position 585 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
