not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 21, 2024The c.760T>A (p.Y254N) alteration is located in exon 3 (coding exon 3) of the NXPE2 gene. This alteration results from a T to A substitution at nucleotide position 760, causing the tyrosine (Y) at amino acid position 254 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
