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 -3 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.43).
• BS1: Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000285 (21/737490) while in subpopulation SAS AF = 0.000243 (16/65888). AF 95% confidence interval is 0.000152. There are 1 homozygotes in GnomAdExome4. There are 9 alleles in the male GnomAdExome4 subpopulation. Median coverage is 10. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
