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]

The c.949C>T (p.R317C) alteration is located in exon 7 (coding exon 7) of the SMC5 gene. This alteration results from a C to T substitution at nucleotide position 949, causing the arginine (R) at amino acid position 317 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
