Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.1862A>G (p.E621G) alteration is located in exon 10 (coding exon 9) of the TBC1D16 gene. This alteration results from a A to G substitution at nucleotide position 1862, causing the glutamic acid (E) at amino acid position 621 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
