Genes affected

UHMK1 (HGNC:19683): (U2AF homology motif kinase 1) The gene encodes a serine/threonine protein kinase that promotes cell cycle progression through G1 by phosphorylation of the cyclin-dependent kinase inhibitor 1B (p27Kip1), which causes nuclear export and degradation. The encoded protein is also thought to function in the adult nervous system and the gene has been associated with schizophrenia. Alternative splicing results in multiple transcript variants.

Collection Method: clinical testing

The c.780C>G (p.H260Q) alteration is located in exon 4 (coding exon 4) of the UHMK1 gene. This alteration results from a C to G substitution at nucleotide position 780, causing the histidine (H) at amino acid position 260 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
