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 submitterclinical testingAmbry GeneticsSep 26, 2022The c.608G>T (p.R203L) alteration is located in exon 5 (coding exon 4) of the SPDL1 gene. This alteration results from a G to T substitution at nucleotide position 608, causing the arginine (R) at amino acid position 203 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
