Genes affected
KNOP1 (HGNC:34404): (lysine rich nucleolar protein 1) The protein encoded by this gene is a nucleolar protein that interacts with zinc finger 106 protein. The encoded protein has several of the same characteristics as nucleostemin and may be involved in testis development. [provided by RefSeq, Feb 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.1114C>G (p.Q372E) alteration is located in exon 5 (coding exon 4) of the KNOP1 gene. This alteration results from a C to G substitution at nucleotide position 1114, causing the glutamine (Q) at amino acid position 372 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
