Genes affected

SP100 (HGNC:11206): (SP100 nuclear antigen) This gene encodes a subnuclear organelle and major component of the PML (promyelocytic leukemia)-SP100 nuclear bodies. PML and SP100 are covalently modified by the SUMO-1 modifier, which is considered crucial to nuclear body interactions. The encoded protein binds heterochromatin proteins and is thought to play a role in tumorigenesis, immunity, and gene regulation. Alternatively spliced variants have been identified for this gene; one of which encodes a high-mobility group protein. [provided by RefSeq, Aug 2011]

The c.744C>G (p.C248W) alteration is located in exon 8 (coding exon 8) of the SP100 gene. This alteration results from a C to G substitution at nucleotide position 744, causing the cysteine (C) at amino acid position 248 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
