Collection Method: clinical testing

The c.3850G>A (p.A1284T) alteration is located in exon 33 (coding exon 33) of the NUP160 gene. This alteration results from a G to A substitution at nucleotide position 3850, causing the alanine (A) at amino acid position 1284 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
