Genes affected

SETD7 (HGNC:30412): (SET domain containing 7, histone lysine methyltransferase) Enables histone-lysine N-methyltransferase activity and p53 binding activity. Involved in peptidyl-lysine dimethylation and peptidyl-lysine monomethylation. Acts upstream of or within cellular response to DNA damage stimulus and heterochromatin organization. Located in chromosome and nucleolus. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.916G>A (p.D306N) alteration is located in exon 7 (coding exon 7) of the SETD7 gene. This alteration results from a G to A substitution at nucleotide position 916, causing the aspartic acid (D) at amino acid position 306 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
