Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 29, 2024The c.614C>G (p.P205R) alteration is located in exon 4 (coding exon 4) of the TMC7 gene. This alteration results from a C to G substitution at nucleotide position 614, causing the proline (P) at amino acid position 205 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
