Collection Method:clinical testing

The c.648G>C (p.L216F) alteration is located in exon 4 (coding exon 4) of the PANX3 gene. This alteration results from a G to C substitution at nucleotide position 648, causing the leucine (L) at amino acid position 216 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
