Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 07, 2023The c.761A>G (p.Y254C) alteration is located in exon 4 (coding exon 3) of the URB2 gene. This alteration results from a A to G substitution at nucleotide position 761, causing the tyrosine (Y) at amino acid position 254 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
