Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.2507C>A (p.A836E) alteration is located in exon 16 (coding exon 16) of the TBC1D9 gene. This alteration results from a C to A substitution at nucleotide position 2507, causing the alanine (A) at amino acid position 836 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
