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]

Collection Method: clinical testing

The c.3818T>C (p.I1273T) alteration is located in exon 19 (coding exon 19) of the NID2 gene. This alteration results from a T to C substitution at nucleotide position 3818, causing the isoleucine (I) at amino acid position 1273 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
