Genes affected

NID1 (HGNC:7821): (nidogen 1) This gene encodes a member of the nidogen family of basement membrane glycoproteins. The protein interacts with several other components of basement membranes, and may play a role in cell interactions with the extracellular matrix. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.3692C>A (p.T1231N) alteration is located in exon 20 (coding exon 20) of the NID1 gene. This alteration results from a C to A substitution at nucleotide position 3692, causing the threonine (T) at amino acid position 1231 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
