The c.303T>G (p.D101E) alteration is located in exon 3 (coding exon 3) of the DIEXF gene. This alteration results from a T to G substitution at nucleotide position 303, causing the aspartic acid (D) at amino acid position 101 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
