Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 12, 2024The c.161G>A (p.G54D) alteration is located in exon 2 (coding exon 2) of the TBC1D31 gene. This alteration results from a G to A substitution at nucleotide position 161, causing the glycine (G) at amino acid position 54 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
