Genes affected

ULK4 (HGNC:15784): (unc-51 like kinase 4) This gene encodes a member of the unc-51-like serine/threonine kinase (STK) family. Members of this protein family play a role in neuronal growth and endocytosis. The encoded protein is likely involved in neurite branching, neurite elongation and neuronal migration. Genome-wide association studies (GWAS) indicate an association of variations in this gene with blood pressure and hypertension. Sequence variations in this gene may also be be associated with psychiatric disorders, including schizophrenia and bipolar disorder. Pseudogenes associated with this gene have been identified and are located on chromosome 15. [provided by RefSeq, Jul 2016]

The c.3515T>C (p.I1172T) alteration is located in exon 35 (coding exon 34) of the ULK4 gene. This alteration results from a T to C substitution at nucleotide position 3515, causing the isoleucine (I) at amino acid position 1172 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
