Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2024The c.550T>G (p.S184A) alteration is located in exon 2 (coding exon 2) of the NXPH2 gene. This alteration results from a T to G substitution at nucleotide position 550, causing the serine (S) at amino acid position 184 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
