Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 14, 2023The c.689C>T (p.A230V) alteration is located in exon 3 (coding exon 3) of the PSTK gene. This alteration results from a C to T substitution at nucleotide position 689, causing the alanine (A) at amino acid position 230 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
