Genes affected
KLLN (HGNC:37212): (killin, p53 regulated DNA replication inhibitor) The protein encoded by this intronless gene is found in the nucleus, where it can inhibit DNA synthesis and promote S phase arrest coupled to apoptosis. The expression of this DNA binding protein is upregulated by transcription factor p53. [provided by RefSeq, Dec 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2024The c.253G>A (p.G85S) alteration is located in exon 1 (coding exon 1) of the KLLN gene. This alteration results from a G to A substitution at nucleotide position 253, causing the glycine (G) at amino acid position 85 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
