Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.41C>T (p.P14L) alteration is located in exon 1 (coding exon 1) of the TMC7 gene. This alteration results from a C to T substitution at nucleotide position 41, causing the proline (P) at amino acid position 14 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
