Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2 PP3_Strong

The NM_003027.5(SH3GL3):c.974G>A(p.Gly325Glu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).

• Frequency: Genomes: not found (cov: 33)
• Consequence: SH3GL3 NM_003027.5 missense
• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: 9.43

Genes affected

SH3GL3 (HGNC:10832): (SH3 domain containing GRB2 like 3, endophilin A3) Enables identical protein binding activity. Predicted to be involved in synaptic vesicle uncoating. Predicted to be located in acrosomal vesicle; early endosome membrane; and presynapse. Predicted to be part of early endosome. Predicted to be active in glutamatergic synapse; postsynaptic density, intracellular component; and postsynaptic endosome. [provided by Alliance of Genome Resources, Apr 2022]
