The c.2006C>G (p.T669R) alteration is located in exon 16 (coding exon 16) of the FAM13A gene. This alteration results from a C to G substitution at nucleotide position 2006, causing the threonine (T) at amino acid position 669 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
