Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 16, 2023The c.1298G>A (p.C433Y) alteration is located in exon 18 (coding exon 17) of the TPTE2 gene. This alteration results from a G to A substitution at nucleotide position 1298, causing the cysteine (C) at amino acid position 433 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
