Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 26, 2023The c.731C>A (p.S244Y) alteration is located in exon 4 (coding exon 3) of the STEAP1B gene. This alteration results from a C to A substitution at nucleotide position 731, causing the serine (S) at amino acid position 244 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
