Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 10, 2022The c.415A>G (p.M139V) alteration is located in exon 6 (coding exon 6) of the TBC1D19 gene. This alteration results from a A to G substitution at nucleotide position 415, causing the methionine (M) at amino acid position 139 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
