The c.4693C>G (p.Q1565E) alteration is located in exon 30 (coding exon 28) of the PLXNB2 gene. This alteration results from a C to G substitution at nucleotide position 4693, causing the glutamine (Q) at amino acid position 1565 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
