Genes affected
ENDOU (HGNC:14369): (endonuclease, poly(U) specific) This gene encodes a protein with endoribonuclease activity that binds polyuridine-enriched single-stranded RNA. This gene was initially characterized based on its high expression in placenta but was mischaracterized as a serine protease. In mouse, this gene promotes tolerance to self-antigens by regulating B cell activation-induced cell death (AICD). The protein may be useful as a tumor marker. Multiple alternatively spliced transcript variants encoding distinct protein isoforms have been found for this gene. [provided by RefSeq, Jul 2020]
RPAP3-DT (HGNC:55477): (RPAP3 divergent transcript)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 08, 2024The c.734G>T (p.S245I) alteration is located in exon 6 (coding exon 6) of the ENDOU gene. This alteration results from a G to T substitution at nucleotide position 734, causing the serine (S) at amino acid position 245 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
