Genes affected

NSL1 (HGNC:24548): (NSL1 component of MIS12 kinetochore complex) This gene encodes a protein with two coiled-coil domains that localizes to kinetochores, which are chromosome-associated structures that attach to microtubules and mediate chromosome movements during cell division. The encoded protein is part of a conserved protein complex that includes two chromodomain-containing proteins and a component of the outer plate of the kinetochore. This protein complex is proposed to bridge centromeric heterochromatin with the outer kinetochore structure. Multiple transcript variants encoding different isoforms have been found for this gene. There is a pseudogene of the 3' UTR region of this gene on chromosome X. [provided by RefSeq, Jul 2014]

The c.560C>A (p.A187D) alteration is located in exon 5 (coding exon 5) of the NSL1 gene. This alteration results from a C to A substitution at nucleotide position 560, causing the alanine (A) at amino acid position 187 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
