Genes affected
GLRA2 (HGNC:4327): (glycine receptor alpha 2) The glycine receptor consists of two subunits, alpha and beta, and acts as a pentamer. The protein encoded by this gene is an alpha subunit and can bind strychnine. Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2010]
GLRA2 Gene-Disease associations (from GenCC):
  • intellectual developmental disorder, X-linked, syndromic, Pilorge type
    Inheritance: XL Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 9 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 2.7002 (below the threshold of 3.09). Trascript score misZ: NaN (below the threshold of 3.09). GenCC associations: The gene is linked to intellectual developmental disorder, X-linked, syndromic, Pilorge type.
BS2
High Hemizygotes in GnomAdExome4 at 2 XL geneVariant has number of hemizygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
