Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 09, 2022The c.532A>G (p.M178V) alteration is located in exon 4 (coding exon 4) of the TBC1D22B gene. This alteration results from a A to G substitution at nucleotide position 532, causing the methionine (M) at amino acid position 178 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
