Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 11, 2022The c.835C>T (p.R279W) alteration is located in exon 6 (coding exon 4) of the NXPE1 gene. This alteration results from a C to T substitution at nucleotide position 835, causing the arginine (R) at amino acid position 279 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
