Genes affected

ZNF639 (HGNC:30950): (zinc finger protein 639) This gene encodes a member of the Kruppel-like zinc finger family of proteins. Amplification and overexpression of this gene have been observed in esophageal squamous cell carcinoma. The encoded protein has been shown to bind DNA in a sequence-specific manner and may regulate HIV-1 gene expression. Alternative splicing results in multiple transcript variants.

The c.755C>T (p.A252V) alteration is located in exon 7 (coding exon 4) of the ZNF639 gene. This alteration results from a C to T substitution at nucleotide position 755, causing the alanine (A) at amino acid position 252 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
