Ambry Genetics

May 04, 2022

The c.85G>A (p.V29I) alteration is located in exon 3 (coding exon 1) of the TMEM63C gene. This alteration results from a G to A substitution at nucleotide position 85, causing the valine (V) at amino acid position 29 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
