Ambry Genetics

Dec 28, 2023

The c.188A>G (p.Y63C) alteration is located in exon 4 (coding exon 2) of the SMIM8 gene. This alteration results from a A to G substitution at nucleotide position 188, causing the tyrosine (Y) at amino acid position 63 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
