Description

The c.1648G>C (p.V550L) alteration is located in exon 1 (coding exon 1) of the PCDHGB2 gene. This alteration results from a G to C substitution at nucleotide position 1648, causing the valine (V) at amino acid position 550 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
