Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2023The c.240C>G (p.S80R) alteration is located in exon 3 (coding exon 2) of the URB2 gene. This alteration results from a C to G substitution at nucleotide position 240, causing the serine (S) at amino acid position 80 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
