Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.2416C>T (p.P806S) alteration is located in exon 22 (coding exon 22) of the TTC13 gene. This alteration results from a C to T substitution at nucleotide position 2416, causing the proline (P) at amino acid position 806 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
