Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 28, 2021The c.3610C>G (p.L1204V) alteration is located in exon 22 (coding exon 22) of the TBC1D9B gene. This alteration results from a C to G substitution at nucleotide position 3610, causing the leucine (L) at amino acid position 1204 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
