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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1172C>T (p.A391V) alteration is located in exon 6 (coding exon 6) of the JMJD4 gene. This alteration results from a C to T substitution at nucleotide position 1172, causing the alanine (A) at amino acid position 391 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
