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 GeneticsJul 09, 2024The c.1502C>T (p.A501V) alteration is located in exon 11 (coding exon 11) of the SHQ1 gene. This alteration results from a C to T substitution at nucleotide position 1502, causing the alanine (A) at amino acid position 501 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
