The c.485G>A (p.R162Q) alteration is located in exon 4 (coding exon 4) of the OLFML2A gene. This alteration results from a G to A substitution at nucleotide position 485, causing the arginine (R) at amino acid position 162 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
