Genes affected

RELN (HGNC:9957): (reelin) This gene encodes a large secreted extracellular matrix protein thought to control cell-cell interactions critical for cell positioning and neuronal migration during brain development. This protein may be involved in schizophrenia, autism, bipolar disorder, major depression and in migration defects associated with temporal lobe epilepsy. Mutations of this gene are associated with autosomal recessive lissencephaly with cerebellar hypoplasia. Two transcript variants encoding distinct isoforms have been identified for this gene. Other transcript variants have been described but their full length nature has not been determined. [provided by RefSeq, Jul 2008]

SLC26A5-AS1 (HGNC:55680): (SLC26A5 antisense RNA 1)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.25010562).
• BP6: Variant 7-103510886-G-T is Benign according to our data. Variant chr7-103510886-G-T is described in ClinVar as Likely_benign. ClinVar VariationId is 567973.Status of the report is criteria_provided_single_submitter, 1 stars.
