Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2024The c.698A>G (p.E233G) alteration is located in exon 2 (coding exon 2) of the TMCC3 gene. This alteration results from a A to G substitution at nucleotide position 698, causing the glutamic acid (E) at amino acid position 233 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
