Ambry Genetics

Sep 30, 2024

The c.10G>A (p.E4K) alteration is located in exon 2 (coding exon 1) of the EFCAB2 gene. This alteration results from a G to A substitution at nucleotide position 10, causing the glutamic acid (E) at amino acid position 4 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
