Genes affected
HJURP (HGNC:25444): (Holliday junction recognition protein) Enables histone binding activity and identical protein binding activity. Involved in several processes, including CENP-A containing chromatin assembly; regulation of DNA binding activity; and regulation of protein-containing complex assembly. Located in kinetochore; mitochondrion; and nuclear lumen. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2023The c.2181C>G (p.N727K) alteration is located in exon 9 (coding exon 9) of the HJURP gene. This alteration results from a C to G substitution at nucleotide position 2181, causing the asparagine (N) at amino acid position 727 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
