The c.735T>A (p.D245E) alteration is located in exon 6 (coding exon 6) of the NAAA gene. This alteration results from a T to A substitution at nucleotide position 735, causing the aspartic acid (D) at amino acid position 245 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
