Collection Method: clinical testing

The c.2036G>A (p.S679N) alteration is located in exon 9 (coding exon 8) of the ZFAND4 gene. This alteration results from a G to A substitution at nucleotide position 2036, causing the serine (S) at amino acid position 679 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
