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

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.26117867).

The c.1085G>C (p.C362S) alteration is located in exon 10 (coding exon 10) of the ASH2L gene. This alteration results from a G to C substitution at nucleotide position 1085, causing the cysteine (C) at amino acid position 362 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
