Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 12, 2024The c.398G>A (p.G133D) alteration is located in exon 5 (coding exon 4) of the TRPT1 gene. This alteration results from a G to A substitution at nucleotide position 398, causing the glycine (G) at amino acid position 133 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
