Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.515G>A (p.G172D) alteration is located in exon 3 (coding exon 2) of the TMUB2 gene. This alteration results from a G to A substitution at nucleotide position 515, causing the glycine (G) at amino acid position 172 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
