Genes affected

NELFCD (HGNC:15934): (negative elongation factor complex member C/D) The NELF complex of proteins interacts with the DSIF protein complex to repress transcriptional elongation by RNA polymerase II. The protein encoded by this gene is an essential part of the NELF complex. Alternative translation initiation site usage results in the formation of two isoforms with different N-termini. [provided by RefSeq, Jul 2008]

NELFCD links:

CTSZ (HGNC:2547): (cathepsin Z) The protein encoded by this gene is a lysosomal cysteine proteinase and member of the peptidase C1 family. It exhibits both carboxy-monopeptidase and carboxy-dipeptidase activities. The encoded protein has also been known as cathepsin X and cathepsin P. This gene is expressed ubiquitously in cancer cell lines and primary tumors and, like other members of this family, may be involved in tumorigenesis. [provided by RefSeq, Oct 2008]

The c.959T>C (p.M320T) alteration is located in exon 8 (coding exon 8) of the NELFCD gene. This alteration results from a T to C substitution at nucleotide position 959, causing the methionine (M) at amino acid position 320 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
