Genes affected
TMEM107 (HGNC:28128): (transmembrane protein 107) This gene encodes a transmembrane protein and component of the primary cilia transition zone. The encoded protein regulates ciliogenesis and ciliary protein composition. Human fibroblasts expressing a mutant allele of this gene exhibit reduced numbers of cilia, altered cilia length, and impaired sonic hedgehog signaling. In human patients, different mutations in this gene cause different ciliopathies, including Meckel-Gruber syndrome and orofaciodigital syndrome. [provided by RefSeq, May 2017]
SNORD118 (HGNC:32952): (small nucleolar RNA, C/D box 118)

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 18, 2023This variant occurs in the SNORD118 gene, which encodes an RNA molecule that does not result in a protein product. This variant is present in population databases (rs9894790, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with SNORD118-related conditions. ClinVar contains an entry for this variant (Variation ID: 1900385). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
