Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 21, 2022The c.2803G>A (p.V935I) alteration is located in exon 17 (coding exon 17) of the TBC1D9 gene. This alteration results from a G to A substitution at nucleotide position 2803, causing the valine (V) at amino acid position 935 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
