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]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 23, 2024 | The c.808C>T (p.R270C) alteration is located in exon 7 (coding exon 6) of the SPDL1 gene. This alteration results from a C to T substitution at nucleotide position 808, causing the arginine (R) at amino acid position 270 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
