Ambry Genetics

Jul 20, 2022

The c.1105G>A (p.V369M) alteration is located in exon 8 (coding exon 8) of the BTNL8 gene. This alteration results from a G to A substitution at nucleotide position 1105, causing the valine (V) at amino acid position 369 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
