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 22, 2024The c.1666G>A (p.V556M) alteration is located in exon 8 (coding exon 8) of the HJURP gene. This alteration results from a G to A substitution at nucleotide position 1666, causing the valine (V) at amino acid position 556 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
