Genes affected

UBAP2L (HGNC:29877): (ubiquitin associated protein 2 like) Enables RNA binding activity. Involved in binding activity of sperm to zona pellucida and stress granule assembly. Acts upstream of or within hematopoietic stem cell homeostasis. Part of PcG protein complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, UBAP2L
• BP4: Computational evidence support a benign effect (MetaRNN=0.31180692).

The c.1582G>A (p.V528I) alteration is located in exon 14 (coding exon 13) of the UBAP2L gene. This alteration results from a G to A substitution at nucleotide position 1582, causing the valine (V) at amino acid position 528 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
