Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 12, 2023The c.248G>A (p.R83Q) alteration is located in exon 2 (coding exon 1) of the TOB2 gene. This alteration results from a G to A substitution at nucleotide position 248, causing the arginine (R) at amino acid position 83 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
