The c.880G>A (p.A294T) alteration is located in exon 4 (coding exon 3) of the NYAP1 gene. This alteration results from a G to A substitution at nucleotide position 880, causing the alanine (A) at amino acid position 294 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
