Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2023The c.1581A>T (p.E527D) alteration is located in exon 12 (coding exon 12) of the TTC17 gene. This alteration results from a A to T substitution at nucleotide position 1581, causing the glutamic acid (E) at amino acid position 527 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
