The c.1974T>G (p.D658E) alteration is located in exon 16 (coding exon 16) of the FAM13A gene. This alteration results from a T to G substitution at nucleotide position 1974, causing the aspartic acid (D) at amino acid position 658 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
