Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2024The c.982G>A (p.G328R) alteration is located in exon 15 (coding exon 14) of the TPTE2 gene. This alteration results from a G to A substitution at nucleotide position 982, causing the glycine (G) at amino acid position 328 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
