Ambry Genetics

Mar 18, 2024

The c.1505C>T (p.T502M) alteration is located in exon 7 (coding exon 7) of the OLFML2B gene. This alteration results from a C to T substitution at nucleotide position 1505, causing the threonine (T) at amino acid position 502 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
