Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 13, 2022The c.1574A>G (p.K525R) alteration is located in exon 13 (coding exon 13) of the TTC13 gene. This alteration results from a A to G substitution at nucleotide position 1574, causing the lysine (K) at amino acid position 525 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
