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

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.88).
BS1
Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.00000898 (13/1447262) while in subpopulation SAS AF= 0.000151 (13/85890). AF 95% confidence interval is 0.0000892. There are 0 homozygotes in gnomad4_exome. There are 11 alleles in male gnomad4_exome subpopulation. Median coverage is 28. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
