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]

The c.575A>C (p.K192T) alteration is located in exon 6 (coding exon 6) of the ENDOU gene. This alteration results from a A to C substitution at nucleotide position 575, causing the lysine (K) at amino acid position 192 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
