Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2021The c.301C>T (p.R101W) alteration is located in exon 2 (coding exon 2) of the TMC7 gene. This alteration results from a C to T substitution at nucleotide position 301, causing the arginine (R) at amino acid position 101 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
