Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 30, 2021The c.36C>G (p.C12W) alteration is located in exon 1 (coding exon 1) of the TTC14 gene. This alteration results from a C to G substitution at nucleotide position 36, causing the cysteine (C) at amino acid position 12 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
