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]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.16202316).

The c.89G>T (p.G30V) alteration is located in exon 1 (coding exon 1) of the ASH2L gene. This alteration results from a G to T substitution at nucleotide position 89, causing the glycine (G) at amino acid position 30 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
