Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.59G>A (p.R20Q) alteration is located in exon 2 (coding exon 2) of the NXPE2 gene. This alteration results from a G to A substitution at nucleotide position 59, causing the arginine (R) at amino acid position 20 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
