Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 08, 2024The c.334C>T (p.R112C) alteration is located in exon 3 (coding exon 3) of the IL20RB gene. This alteration results from a C to T substitution at nucleotide position 334, causing the arginine (R) at amino acid position 112 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
