Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 14, 2023The c.1006C>T (p.R336C) alteration is located in exon 10 (coding exon 10) of the TBC1D13 gene. This alteration results from a C to T substitution at nucleotide position 1006, causing the arginine (R) at amino acid position 336 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
