Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.281A>G (p.D94G) alteration is located in exon 2 (coding exon 1) of the TPST1 gene. This alteration results from a A to G substitution at nucleotide position 281, causing the aspartic acid (D) at amino acid position 94 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
