The c.651C>G (p.D217E) alteration is located in exon 2 (coding exon 1) of the TOR4A gene. This alteration results from a C to G substitution at nucleotide position 651, causing the aspartic acid (D) at amino acid position 217 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
