Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 11, 2022The c.2924G>A (p.G975E) alteration is located in exon 22 (coding exon 22) of the TMC3 gene. This alteration results from a G to A substitution at nucleotide position 2924, causing the glycine (G) at amino acid position 975 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
