Ambry Genetics

Dec 20, 2023

The c.295C>T (p.P99S) alteration is located in exon 2 (coding exon 2) of the OLFML2A gene. This alteration results from a C to T substitution at nucleotide position 295, causing the proline (P) at amino acid position 99 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
