Ambry Genetics

May 27, 2022

The c.295C>A (p.Q99K) alteration is located in exon 2 (coding exon 1) of the TMEM140 gene. This alteration results from a C to A substitution at nucleotide position 295, causing the glutamine (Q) at amino acid position 99 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
