Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.611G>A (p.R204H) alteration is located in exon 5 (coding exon 5) of the TBC1D9B gene. This alteration results from a G to A substitution at nucleotide position 611, causing the arginine (R) at amino acid position 204 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
