Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.2113G>A (p.D705N) alteration is located in exon 12 (coding exon 11) of the TBC1D16 gene. This alteration results from a G to A substitution at nucleotide position 2113, causing the aspartic acid (D) at amino acid position 705 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
