Genes affected

GJC2 (HGNC:17494): (gap junction protein gamma 2) This gene encodes a gap junction protein. Gap junction proteins are members of a large family of homologous connexins and comprise 4 transmembrane, 2 extracellular, and 3 cytoplasmic domains. This gene plays a key role in central myelination and is involved in peripheral myelination in humans. Defects in this gene are the cause of autosomal recessive Pelizaeus-Merzbacher-like disease-1.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 19 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Gene score misZ: 1.8719 (below the threshold of 3.09). Trascript score misZ: -1.3976 (below the threshold of 3.09). GenCC associations: The gene is linked to hypomyelinating leukodystrophy 2, hereditary spastic paraplegia 44, lymphatic malformation 3, lymphatic malformation.

BP4

Computational evidence support a benign effect (MetaRNN=0.19351688).
