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]

Submissions by phenotype

Primary ciliary dyskinesia Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 11, 2023The c.8C>A (p.A3E) alteration is located in exon 1 (coding exon 1) of the OFD1 gene. This alteration results from a C to A substitution at nucleotide position 8, causing the alanine (A) at amino acid position 3 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
