BPTF

On this page, you will find information about a genetic change that was identified in a UDN participant. We are trying to find others with the same or similar condition.

Sharing information on this website is not a requirement of UDN participation. Only descriptions about participants who give explicit consent will appear here.

A change in the BPTF gene was identified in a UDN participant with abnormal muscle twitching, saliva build up, and autism.

Date of Report

Full Name

Bromodomain PHD Finger Transcription Factor

Location
Chromosome 17q24.2

Function

The BPTF gene codes for the Bromodomain PHD Finger Transcription Factor, a protein that regulates the NURF-1 and NURF-5 ISWI chromatin remodeling complexes (Oppikofer et al. 2017).  These complexes are involved in the regulation of gene expression involved in brain development (Barak et al. 2003).

Variants causing haploinsufficiency of the BPTF gene are associated with a neurodevelopmental disorder with dysmorphic facial features and limb anomalies (Stankiewicz et al. 2017). More recently, Glinton et al. (2021), identified 25 individuals with 20 distinct phenotypes suggesting a broad and variable clinical picture of individuals with BPTF variants.
