Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 24, 2023The c.802C>T (p.H268Y) alteration is located in exon 3 (coding exon 3) of the NXPE2 gene. This alteration results from a C to T substitution at nucleotide position 802, causing the histidine (H) at amino acid position 268 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
