The c.2692A>C (p.N898H) alteration is located in exon 17 (coding exon 16) of the AGBL3 gene. This alteration results from a A to C substitution at nucleotide position 2692, causing the asparagine (N) at amino acid position 898 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
