Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2023The c.560G>A (p.R187K) alteration is located in exon 1 (coding exon 1) of the IFNA13 gene. This alteration results from a G to A substitution at nucleotide position 560, causing the arginine (R) at amino acid position 187 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
