The c.981A>T (p.E327D) alteration is located in exon 7 (coding exon 7) of the FBP2 gene. This alteration results from a A to T substitution at nucleotide position 981, causing the glutamic acid (E) at amino acid position 327 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
