Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2021The c.3024G>T (p.E1008D) alteration is located in exon 21 (coding exon 21) of the TBC1D9B gene. This alteration results from a G to T substitution at nucleotide position 3024, causing the glutamic acid (E) at amino acid position 1008 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
