Genes affected
OFD1 (HGNC:2567): (OFD1 centriole and centriolar satellite protein) This gene is located on the X chromosome and encodes a centrosomal protein. A knockout mouse model has been used to study the effect of mutations in this gene. The mouse gene is also located on the X chromosome, however, unlike the human gene it is not subject to X inactivation. Mutations in this gene are associated with oral-facial-digital syndrome type I and Simpson-Golabi-Behmel syndrome type 2. Many pseudogenes have been identified; a single pseudogene is found on chromosome 5 while as many as fifteen have been found on the Y chromosome. [provided by RefSeq, Aug 2016]

not provided Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Nov 21, 2022 | Frameshift variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss of function is a known mechanism of disease; Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 18546297) - |
Familial aplasia of the vermis;C1510460:Orofaciodigital syndrome I Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Mar 02, 2022 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 41131). This variant is also known as p.E206NfsX222. This premature translational stop signal has been observed in individual(s) with oral-facial-digital syndrome, type I (PMID: 18546297). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu206Asnfs*17) in the OFD1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in OFD1 are known to be pathogenic (PMID: 16783569, 18546297, 27081566). - |
