Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001009184.2(GRINA):​c.8A>G​(p.His3Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000431 in 1,578,762 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H3Q) has been classified as Uncertain significance.

Genes affected
GRINA (HGNC:4589): (glutamate ionotropic receptor NMDA type subunit associated protein 1) Predicted to enable transmembrane transporter binding activity. Predicted to act upstream of or within endoplasmic reticulum calcium ion homeostasis and negative regulation of endoplasmic reticulum stress-induced intrinsic apoptotic signaling pathway. Predicted to be located in Golgi apparatus and endoplasmic reticulum. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
PARP10 (HGNC:25895): (poly(ADP-ribose) polymerase family member 10) Poly(ADP-ribose) polymerases (PARPs), such as PARP10, regulate gene transcription by altering chromatin organization by adding ADP-ribose to histones. PARPs can also function as transcriptional cofactors (Yu et al., 2005 [PubMed 15674325]).[supplied by OMIM, Mar 2008]

The c.8A>G (p.H3R) alteration is located in exon 2 (coding exon 1) of the GRINA gene. This alteration results from a A to G substitution at nucleotide position 8, causing the histidine (H) at amino acid position 3 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
