Genes affected
SHQ1 (HGNC:25543): (SHQ1, H/ACA ribonucleoprotein assembly factor) SHQ1 assists in the assembly of H/ACA-box ribonucleoproteins that function in the processing of ribosomal RNAs, modification of spliceosomal small nuclear RNAs, and stabilization of telomerase (see MIM 602322) (Grozdanov et al., 2009 [PubMed 19383767]).[supplied by OMIM, Dec 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.1520G>A (p.G507D) alteration is located in exon 11 (coding exon 11) of the SHQ1 gene. This alteration results from a G to A substitution at nucleotide position 1520, causing the glycine (G) at amino acid position 507 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
