Ambry Genetics

Dec 13, 2022

The c.95T>G (p.F32C) alteration is located in exon 2 (coding exon 2) of the OLFML2A gene. This alteration results from a T to G substitution at nucleotide position 95, causing the phenylalanine (F) at amino acid position 32 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
