Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 16, 2024The c.646C>A (p.L216I) 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 646, causing the leucine (L) at amino acid position 216 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
