Genes affected

ZBTB1 (HGNC:20259): (zinc finger and BTB domain containing 1) Enables K63-linked polyubiquitin modification-dependent protein binding activity; protein heterodimerization activity; and protein homodimerization activity. Involved in several processes, including cellular response to UV; nucleobase-containing compound biosynthetic process; and protein homooligomerization. Located in centrosome; nuclear body; and nuclear membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.948A>C (p.K316N) alteration is located in exon 2 (coding exon 1) of the ZBTB1 gene. This alteration results from a A to C substitution at nucleotide position 948, causing the lysine (K) at amino acid position 316 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
