Genes affected
CNTLN (HGNC:23432): (centlein) Enables protein domain specific binding activity; protein kinase binding activity; and protein-macromolecule adaptor activity. Involved in centriole-centriole cohesion and protein localization to organelle. Located in cytosol; microtubule organizing center; and nucleoplasm.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.86C>T (p.A29V) alteration is located in exon 1 (coding exon 1) of the CNTLN gene. This alteration results from a C to T substitution at nucleotide position 86, causing the alanine (A) at amino acid position 29 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
