Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.

The NM_001033088.3(NGRN):​c.134C>T​(p.Pro45Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000413 in 1,454,024 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P45Q) has been classified as Uncertain significance.

Genes affected

NGRN (HGNC:18077): (neugrin, neurite outgrowth associated) Enables rRNA binding activity. Involved in positive regulation of mitochondrial translation. Located in several cellular components, including intercellular bridge; mitotic spindle; and nuclear body. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000261147 (HGNC:):

CIB1 (HGNC:16920): (calcium and integrin binding 1) This gene encodes a member of the EF-hand domain-containing calcium-binding superfamily. The encoded protein interacts with many other proteins, including the platelet integrin alpha-IIb-beta-3, DNA-dependent protein kinase, presenilin-2, focal adhesion kinase, p21 activated kinase, and protein kinase D. The encoded protein may be involved in cell survival and proliferation, and is associated with several disease states including cancer and Alzheimer's disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2013]

CIB1 Gene-Disease associations (from GenCC):

• epidermodysplasia verruciformis, susceptibility to, 3

  Inheritance: AR Classification: DEFINITIVE, STRONG Submitted by: Genomics England PanelApp, Labcorp Genetics (formerly Invitae), G2P
• epidermodysplasia verruciformis

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet
