Genetic Variant JMJD4:p.Val378Leu (chr1-227732514-C-A) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_023007.3(JMJD4):c.1132G>T(p.Val378Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000186 in 1,613,260 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V378M) has been classified as Uncertain significance.

Genes affected

JMJD4 (HGNC:25724): (jumonji domain containing 4) Enables 2-oxoglutarate-dependent dioxygenase activity. Involved in positive regulation of translational termination and protein hydroxylation. Located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

JMJD4 links:

SNAP47 (HGNC:30669): (synaptosome associated protein 47) Predicted to enable SNAP receptor activity and syntaxin binding activity. Predicted to be involved in synaptic vesicle fusion to presynaptic active zone membrane and synaptic vesicle priming. Predicted to act upstream of or within long-term synaptic potentiation. Colocalizes with BLOC-1 complex. [provided by Alliance of Genome Resources, Apr 2022]
