Ambry Genetics

Nov 28, 2023

The c.232G>T (p.V78F) alteration is located in exon 3 (coding exon 3) of the LSMEM2 gene. This alteration results from a G to T substitution at nucleotide position 232, causing the valine (V) at amino acid position 78 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
