Genes affected

CHD5 (HGNC:16816): (chromodomain helicase DNA binding protein 5) This gene encodes a member of the chromodomain helicase DNA-binding protein family. Members of this family are characterized by a chromodomain, a helicase ATP-binding domain and an additional functional domain. This gene encodes a neuron-specific protein that may function in chromatin remodeling and gene transcription. This gene is a potential tumor suppressor gene that may play a role in the development of neuroblastoma. [provided by RefSeq, Feb 2012]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the CHD5 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 13 curated pathogenic missense variants (we use a threshold of 10). The gene has 8 curated benign missense variants. Gene score misZ: 5.3168 (above the threshold of 3.09). Trascript score misZ: 5.6838 (above the threshold of 3.09). GenCC associations: The gene is linked to schizophrenia, parenti-mignot neurodevelopmental syndrome.
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
