Genes affected

ASH2L (HGNC:744): (ASH2 like, histone lysine methyltransferase complex subunit) Enables beta-catenin binding activity and transcription cis-regulatory region binding activity. Contributes to histone methyltransferase activity (H3-K4 specific). Involved in histone H3-K4 methylation; positive regulation of cell population proliferation; and response to estrogen. Acts upstream of or within cellular response to DNA damage stimulus. Located in nucleus. Part of MLL3/4 complex and Set1C/COMPASS complex. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method:clinical testing

The c.11C>A (p.A4E) alteration is located in exon 1 (coding exon 1) of the ASH2L gene. This alteration results from a C to A substitution at nucleotide position 11, causing the alanine (A) at amino acid position 4 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
