Genes affected

SPDL1 (HGNC:26010): (spindle apparatus coiled-coil protein 1) This gene encodes a coiled-coil domain-containing protein that functions in mitotic spindle formation and chromosome segregation. The encoded protein plays a role in coordinating microtubule attachment by promoting recruitment of dynein proteins, and in mitotic checkpoint signaling. [provided by RefSeq, Jul 2016]

The c.878T>C (p.M293T) alteration is located in exon 7 (coding exon 6) of the SPDL1 gene. This alteration results from a T to C substitution at nucleotide position 878, causing the methionine (M) at amino acid position 293 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
