Genes affected
UTP14A (HGNC:10665): (UTP14A small subunit processome component) This gene encodes a member of the uridine triphosphate 14 family. As an essential component of a large ribonucleoprotein complex bound to the U3 small nucleolar RNA, the encoded protein is involved in ribosome biogenesis and 18S rRNA synthesis. An autosomal retrotransposed copy of this X-linked gene exists on chromosome 13. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Oct 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2023The c.442G>A (p.V148I) alteration is located in exon 6 (coding exon 6) of the UTP14A gene. This alteration results from a G to A substitution at nucleotide position 442, causing the valine (V) at amino acid position 148 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
