Collection Method: clinical testing

The c.616A>G (p.K206E) alteration is located in exon 6 (coding exon 6) of the NIPAL2 gene. This alteration results from a A to G substitution at nucleotide position 616, causing the lysine (K) at amino acid position 206 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
