Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 18, 2021The c.11C>A (p.S4Y) alteration is located in exon 1 (coding exon 1) of the TMC7 gene. This alteration results from a C to A substitution at nucleotide position 11, causing the serine (S) at amino acid position 4 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
