Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2023The c.137T>C (p.I46T) alteration is located in exon 1 (coding exon 1) of the RPP25 gene. This alteration results from a T to C substitution at nucleotide position 137, causing the isoleucine (I) at amino acid position 46 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
