Genes affected

UTP20 (HGNC:17897): (UTP20 small subunit processome component) UTP20 is a component of the U3 small nucleolar RNA (snoRNA) (SNORD3A; MIM 180710) protein complex (U3 snoRNP) and is involved in 18S rRNA processing (Wang et al., 2007 [PubMed 17498821]).[supplied by OMIM, Jun 2009]

Ambry Genetics

Sep 29, 2022

The c.319C>G (p.L107V) alteration is located in exon 4 (coding exon 4) of the UTP20 gene. This alteration results from a C to G substitution at nucleotide position 319, causing the leucine (L) at amino acid position 107 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
