Ambry Genetics

Aug 17, 2022

The c.7T>A (p.S3T) alteration is located in exon 1 (coding exon 1) of the MGRN1 gene. This alteration results from a T to A substitution at nucleotide position 7, causing the serine (S) at amino acid position 3 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
