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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2024The c.151G>A (p.G51S) alteration is located in exon 3 (coding exon 3) of the UTP20 gene. This alteration results from a G to A substitution at nucleotide position 151, causing the glycine (G) at amino acid position 51 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
