Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 14, 2023The c.530C>T (p.T177M) alteration is located in exon 2 (coding exon 1) of the TSKU gene. This alteration results from a C to T substitution at nucleotide position 530, causing the threonine (T) at amino acid position 177 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
