Ambry Genetics

Jan 10, 2023

The c.344G>T (p.R115L) alteration is located in exon 3 (coding exon 3) of the OSTN gene. This alteration results from a G to T substitution at nucleotide position 344, causing the arginine (R) at amino acid position 115 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
