Genes affected
KASH5 (HGNC:26520): (KASH domain containing 5) Predicted to enable dynein complex binding activity. Predicted to be involved in several processes, including cytoskeleton organization; homologous chromosome segregation; and spindle localization. Predicted to act upstream of or within double-strand break repair via homologous recombination; oogenesis; and spermatogenesis. Predicted to be integral component of membrane. Predicted to be part of meiotic nuclear membrane microtubule tethering complex. Predicted to be active in chromosome; meiotic spindle pole; and nuclear outer membrane.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2024The c.53G>A (p.R18Q) alteration is located in exon 3 (coding exon 2) of the CCDC155 gene. This alteration results from a G to A substitution at nucleotide position 53, causing the arginine (R) at amino acid position 18 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
