The c.270C>G (p.N90K) alteration is located in exon 2 (coding exon 2) of the ABHD14A gene. This alteration results from a C to G substitution at nucleotide position 270, causing the asparagine (N) at amino acid position 90 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
