Ambry Genetics

Oct 12, 2021

The c.6C>A (p.N2K) alteration is located in exon 1 (coding exon 1) of the GTF3C4 gene. This alteration results from a C to A substitution at nucleotide position 6, causing the asparagine (N) at amino acid position 2 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
