X-151969707-A-G

Position:

• chrX-151969707-A-G

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_004961.4(GABRE):​c.304T>C​(p.Ser102Pro) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. 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. S102A) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 22)
• Consequence: GABRE NM_004961.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 4.11

Genes affected

GABRE (HGNC:4085): (gamma-aminobutyric acid type A receptor subunit epsilon) The product of this gene belongs to the ligand-gated ionic channel (TC 1.A.9) family. It encodes the gamma-aminobutyric acid (GABA) A receptor which is a multisubunit chloride channel that mediates the fastest inhibitory synaptic transmission in the central nervous system. This gene encodes an epsilon subunit. It is mapped to chromosome Xq28 in a cluster comprised of genes encoding alpha 3, beta 4 and theta subunits of the same receptor. Alternatively spliced transcript variants have been identified, but only one is thought to encode a protein. [provided by RefSeq, Oct 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

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