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]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.058545977).
• BP6: Variant X-13758388-G-A is Benign according to our data. Variant chrX-13758388-G-A is described in ClinVar as [Benign]. Clinvar id is 463449.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High Hemizygotes in GnomAdExome at 2 XL gene
