Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 09, 2024The c.125C>G (p.A42G) alteration is located in exon 1 (coding exon 1) of the IFNA17 gene. This alteration results from a C to G substitution at nucleotide position 125, causing the alanine (A) at amino acid position 42 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
