Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2021The c.142C>G (p.Q48E) alteration is located in exon 3 (coding exon 2) of the STEAP1B gene. This alteration results from a C to G substitution at nucleotide position 142, causing the glutamine (Q) at amino acid position 48 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
