not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 19, 2023The c.95C>T (p.T32M) alteration is located in exon 3 (coding exon 2) of the STEAP1B gene. This alteration results from a C to T substitution at nucleotide position 95, causing the threonine (T) at amino acid position 32 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
