Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2022The c.652G>A (p.G218R) alteration is located in exon 3 (coding exon 2) of the TCTE1 gene. This alteration results from a G to A substitution at nucleotide position 652, causing the glycine (G) at amino acid position 218 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
