Genes affected

ZBTB18 (HGNC:13030): (zinc finger and BTB domain containing 18) This gene encodes a C2H2-type zinc finger protein which acts a transcriptional repressor of genes involved in neuronal development. The encoded protein recognizes a specific sequence motif and recruits components of chromatin to target genes. Alternative splicing results in multiple transcript variants.

The c.170A>T (p.Y57F) alteration is located in exon 2 (coding exon 2) of the ZBTB18 gene. This alteration results from a A to T substitution at nucleotide position 170, causing the tyrosine (Y) at amino acid position 57 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
