Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2023The c.248C>A (p.A83D) alteration is located in exon 2 (coding exon 2) of the NXPH4 gene. This alteration results from a C to A substitution at nucleotide position 248, causing the alanine (A) at amino acid position 83 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
