Collection Method: clinical testing

The c.86G>A (p.R29H) alteration is located in exon 1 (coding exon 1) of the PANX3 gene. This alteration results from a G to A substitution at nucleotide position 86, causing the arginine (R) at amino acid position 29 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
