The c.1612A>G (p.T538A) alteration is located in exon 7 (coding exon 7) of the OLFML2B gene. This alteration results from a A to G substitution at nucleotide position 1612, causing the threonine (T) at amino acid position 538 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
