Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.956A>G (p.Q319R) alteration is located in exon 5 (coding exon 5) of the NXPE2 gene. This alteration results from a A to G substitution at nucleotide position 956, causing the glutamine (Q) at amino acid position 319 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
