Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 01, 2023The c.1450G>A (p.G484R) alteration is located in exon 6 (coding exon 5) of the TBCCD1 gene. This alteration results from a G to A substitution at nucleotide position 1450, causing the glycine (G) at amino acid position 484 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
