Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 23, 2021The c.683C>T (p.S228L) alteration is located in exon 2 (coding exon 2) of the NXPH4 gene. This alteration results from a C to T substitution at nucleotide position 683, causing the serine (S) at amino acid position 228 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
