Genes affected
SMC5 (HGNC:20465): (structural maintenance of chromosomes 5) Predicted to enable ATP binding activity. Involved in several processes, including DNA recombination; cellular senescence; and positive regulation of maintenance of mitotic sister chromatid cohesion. Located in cell junction; chromosome; and nuclear body. Part of Smc5-Smc6 complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.874G>C (p.V292L) alteration is located in exon 7 (coding exon 7) of the SMC5 gene. This alteration results from a G to C substitution at nucleotide position 874, causing the valine (V) at amino acid position 292 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
