May 30, 2023

The c.2030T>G (p.F677C) alteration is located in exon 8 (coding exon 8) of the OLFML2B gene. This alteration results from a T to G substitution at nucleotide position 2030, causing the phenylalanine (F) at amino acid position 677 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
