Ambry Genetics

Aug 12, 2021

The c.3643G>T (p.A1215S) alteration is located in exon 14 (coding exon 14) of the ERICH3 gene. This alteration results from a G to T substitution at nucleotide position 3643, causing the alanine (A) at amino acid position 1215 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
