Genes affected
NCL (HGNC:7667): (nucleolin) Nucleolin (NCL), a eukaryotic nucleolar phosphoprotein, is involved in the synthesis and maturation of ribosomes. It is located mainly in dense fibrillar regions of the nucleolus. Human NCL gene consists of 14 exons with 13 introns and spans approximately 11kb. The intron 11 of the NCL gene encodes a small nucleolar RNA, termed U20. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2024The c.1951G>T (p.G651C) alteration is located in exon 13 (coding exon 13) of the NCL gene. This alteration results from a G to T substitution at nucleotide position 1951, causing the glycine (G) at amino acid position 651 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
