Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 24, 2024The c.3289C>T (p.P1097S) alteration is located in exon 21 (coding exon 21) of the TBC1D9 gene. This alteration results from a C to T substitution at nucleotide position 3289, causing the proline (P) at amino acid position 1097 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
