Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.544C>A (p.Q182K) alteration is located in exon 1 (coding exon 1) of the IFNA16 gene. This alteration results from a C to A substitution at nucleotide position 544, causing the glutamine (Q) at amino acid position 182 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
