Genes affected
SUV39H1 (HGNC:11479): (SUV39H1 histone lysine methyltransferase) This gene encodes an evolutionarily-conserved protein containing an N-terminal chromodomain and a C-terminal SET domain. The encoded protein is a histone methyltransferase that trimethylates lysine 9 of histone H3, which results in transcriptional gene silencing. Loss of function of this gene disrupts heterochromatin formation and may cause chromosome instability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 30, 2024The c.402G>C (p.E134D) alteration is located in exon 3 (coding exon 3) of the SUV39H1 gene. This alteration results from a G to C substitution at nucleotide position 402, causing the glutamic acid (E) at amino acid position 134 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
