Genes affected
PHF6 (HGNC:18145): (PHD finger protein 6) This gene is a member of the plant homeodomain (PHD)-like finger (PHF) family. It encodes a protein with two PHD-type zinc finger domains, indicating a potential role in transcriptional regulation, that localizes to the nucleolus. Mutations affecting the coding region of this gene or the splicing of the transcript have been associated with Borjeson-Forssman-Lehmann syndrome (BFLS), a disorder characterized by cognitive disability, epilepsy, hypogonadism, hypometabolism, obesity, swelling of subcutaneous tissue of the face, narrow palpebral fissures, and large ears. Alternate splicing results in multiple transcript variants, encoding different isoforms. [provided by RefSeq, Jun 2010]

Borjeson-Forssman-Lehmann syndrome Pathogenic:5
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Feb 23, 2019 | For these reasons, this variant has been classified as Pathogenic. This variant has been observed to segregate with Börjeson–Forssman–Lehmann syndrome in several families (PMID: 12415272, 15994862, Invitae). ClinVar contains an entry for this variant (Variation ID: 11068). This variant is not present in population databases (ExAC no frequency). This sequence change affects the initiator methionine of the PHF6 mRNA. The next in-frame methionine is located at codon 46. - |
