Genes affected

ZBTB20 (HGNC:13503): (zinc finger and BTB domain containing 20) This gene, which was initially designated as dendritic cell-derived BTB/POZ zinc finger (DPZF), belongs to a family of transcription factors with an N-terminal BTB/POZ domain and a C-terminal DNA-bindng zinc finger domain. The BTB/POZ domain is a hydrophobic region of approximately 120 aa which mediates association with other BTB/POZ domain-containing proteins. This gene acts as a transcriptional repressor and plays a role in many processes including neurogenesis, glucose homeostasis, and postnatal growth. Mutations in this gene have been associated with Primrose syndrome as well as the 3q13.31 microdeletion syndrome. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Feb 2017]

DNA sequence analysis of the ZBTB20 gene demonstrated a sequence change, c.189G>C, in exon 3 which does not result in an amino acid change. This sequence change does not appear to have been previously described in patients with ZBTB20-related disorders and has been described in the gnomAD database in one individual which corresponds to a population frequency of 0.00070% (dbSNP rs1236262753). This sequence change is not predicted to have a deleterious effect on splicing based on in silico splice prediction programs. As the c.189G>C sequence change does not result in a change in the ZBTB20 amino acid sequence, it is possible that this change is non-pathogenic and represents a benign sequence variant of the ZBTB20 gene, however functional studies have not been performed to prove this conclusively. The functional significance of this sequence change is not known at present and its contribution to this patient's disease phenotype cannot definitively be determined. -
