Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2024The c.910G>C (p.V304L) alteration is located in exon 4 (coding exon 3) of the URB2 gene. This alteration results from a G to C substitution at nucleotide position 910, causing the valine (V) at amino acid position 304 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
