Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2023The c.695G>C (p.G232A) alteration is located in exon 6 (coding exon 6) of the TBC1D31 gene. This alteration results from a G to C substitution at nucleotide position 695, causing the glycine (G) at amino acid position 232 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
