Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.1893G>C (p.R631S) alteration is located in exon 11 (coding exon 11) of the TBC1D9B gene. This alteration results from a G to C substitution at nucleotide position 1893, causing the arginine (R) at amino acid position 631 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
