Genes affected
CASK (HGNC:1497): (calcium/calmodulin dependent serine protein kinase) This gene encodes a calcium/calmodulin-dependent serine protein kinase. The encoded protein is a MAGUK (membrane-associated guanylate kinase) protein family member. These proteins are scaffold proteins and the encoded protein is located at synapses in the brain. Mutations in this gene are associated with FG syndrome 4, intellectual disability and microcephaly with pontine and cerebellar hypoplasia, and a form of X-linked intellectual disability. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2017]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), CASK. . Gene score misZ 4.2502 (greater than the threshold 3.09). GenCC has associacion of gene with syndromic X-linked intellectual disability Najm type, X-linked syndromic intellectual disability, developmental and epileptic encephalopathy, FG syndrome 4.
BP4
Computational evidence support a benign effect (MetaRNN=0.25149125).
BP6
Variant X-41534931-T-C is Benign according to our data. Variant chrX-41534931-T-C is described in ClinVar as [Benign]. Clinvar id is 158072.Status of the report is criteria_provided_single_submitter, 1 stars.
