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]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.54).
BP6
Variant 7-103698090-G-A is Benign according to our data. Variant chr7-103698090-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 193677.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=0.486 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00261 (397/152242) while in subpopulation AFR AF = 0.00927 (385/41552). AF 95% confidence interval is 0.0085. There are 0 homozygotes in GnomAd4. There are 185 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
