Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2022The c.2296T>G (p.S766A) alteration is located in exon 20 (coding exon 20) of the TTC13 gene. This alteration results from a T to G substitution at nucleotide position 2296, causing the serine (S) at amino acid position 766 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
