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.382G>A (p.D128N) alteration is located in exon 4 (coding exon 4) of the SP100 gene. This alteration results from a G to A substitution at nucleotide position 382, causing the aspartic acid (D) at amino acid position 128 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
