Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.559C>T (p.R187W) alteration is located in exon 2 (coding exon 1) of the TPST1 gene. This alteration results from a C to T substitution at nucleotide position 559, causing the arginine (R) at amino acid position 187 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
