Ambry Genetics

Jan 18, 2022

The c.185C>T (p.A62V) alteration is located in exon 4 (coding exon 2) of the SMIM8 gene. This alteration results from a C to T substitution at nucleotide position 185, causing the alanine (A) at amino acid position 62 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
