Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 27, 2022The c.472G>A (p.D158N) alteration is located in exon 4 (coding exon 4) of the TBC1D22A gene. This alteration results from a G to A substitution at nucleotide position 472, causing the aspartic acid (D) at amino acid position 158 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
