Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2022The c.724C>T (p.P242S) alteration is located in exon 1 (coding exon 1) of the ISG20L2 gene. This alteration results from a C to T substitution at nucleotide position 724, causing the proline (P) at amino acid position 242 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
