Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 30, 2023The c.647T>G (p.M216R) alteration is located in exon 4 (coding exon 3) of the STEAP1B gene. This alteration results from a T to G substitution at nucleotide position 647, causing the methionine (M) at amino acid position 216 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
