Genes affected

NID2 (HGNC:13389): (nidogen 2) This gene encodes a member of the nidogen family of basement membrane proteins. This protein is a cell-adhesion protein that binds collagens I and IV and laminin and may be involved in maintaining the structure of the basement membrane.[provided by RefSeq, Jun 2010]

NID2 links:

RTRAF (HGNC:23169): (RNA transcription, translation and transport factor) Enables RNA binding activity; RNA polymerase II complex binding activity; and identical protein binding activity. Involved in negative regulation of protein kinase activity; positive regulation of transcription by RNA polymerase II; and tRNA splicing, via endonucleolytic cleavage and ligation. Located in microtubule cytoskeleton; nucleoplasm; and perinuclear region of cytoplasm. Part of tRNA-splicing ligase complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.3914G>C (p.G1305A) alteration is located in exon 20 (coding exon 20) of the NID2 gene. This alteration results from a G to C substitution at nucleotide position 3914, causing the glycine (G) at amino acid position 1305 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
