Ambry Genetics

Aug 22, 2023

The c.67G>A (p.E23K) alteration is located in exon 4 (coding exon 2) of the TMEM108 gene. This alteration results from a G to A substitution at nucleotide position 67, causing the glutamic acid (E) at amino acid position 23 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
