Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 27, 2024The c.265G>A (p.E89K) alteration is located in exon 5 (coding exon 4) of the TTC12 gene. This alteration results from a G to A substitution at nucleotide position 265, causing the glutamic acid (E) at amino acid position 89 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
