The c.897A>T (p.E299D) alteration is located in exon 3 (coding exon 3) of the GPATCH3 gene. This alteration results from a A to T substitution at nucleotide position 897, causing the glutamic acid (E) at amino acid position 299 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
