Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2022The c.698G>A (p.R233Q) alteration is located in exon 1 (coding exon 1) of the ISG20L2 gene. This alteration results from a G to A substitution at nucleotide position 698, causing the arginine (R) at amino acid position 233 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
