Feb 06, 2024

The c.809T>C (p.I270T) alteration is located in exon 3 (coding exon 3) of the OLFML1 gene. This alteration results from a T to C substitution at nucleotide position 809, causing the isoleucine (I) at amino acid position 270 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
