Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2024The c.160G>A (p.A54T) alteration is located in exon 3 (coding exon 3) of the TBC1D17 gene. This alteration results from a G to A substitution at nucleotide position 160, causing the alanine (A) at amino acid position 54 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
