Genes affected
LIN9 (HGNC:30830): (lin-9 DREAM MuvB core complex component) This gene encodes a tumor suppressor protein that inhibits DNA synthesis and oncogenic transformation through association with the retinoblastoma 1 protein. The encoded protein also interacts with a complex of other cell cycle regulators to repress cell cycle-dependent gene expression in non-dividing cells. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jul 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.719C>T (p.T240M) alteration is located in exon 7 (coding exon 7) of the LIN9 gene. This alteration results from a C to T substitution at nucleotide position 719, causing the threonine (T) at amino acid position 240 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
