Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.767T>G (p.V256G) alteration is located in exon 3 (coding exon 3) of the NXPE2 gene. This alteration results from a T to G substitution at nucleotide position 767, causing the valine (V) at amino acid position 256 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
