Genes affected
LEO1 (HGNC:30401): (LEO1 homolog, Paf1/RNA polymerase II complex component) LEO1, parafibromin (CDC73; MIM 607393), CTR9 (MIM 609366), and PAF1 (MIM 610506) form the PAF protein complex that associates with the RNA polymerase II subunit POLR2A (MIM 180660) and with a histone methyltransferase complex (Rozenblatt-Rosen et al., 2005 [PubMed 15632063]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.1113C>A (p.N371K) alteration is located in exon 5 (coding exon 5) of the LEO1 gene. This alteration results from a C to A substitution at nucleotide position 1113, causing the asparagine (N) at amino acid position 371 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
