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]

GRINA links:

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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.331C>G (p.P111A) alteration is located in exon 2 (coding exon 1) of the GRINA gene. This alteration results from a C to G substitution at nucleotide position 331, causing the proline (P) at amino acid position 111 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
