Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 08, 2024The c.2833G>A (p.E945K) 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 2833, causing the glutamic acid (E) at amino acid position 945 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
