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

Verdict is Likely_benign. Variant got -3 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.0025 CDS is truncated, and there are 0 pathogenic variants in the truncated region.
• BP6: Variant 7-103472838-G-A is Benign according to our data. Variant chr7-103472838-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 574190.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=1}.
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0000657 (10/152218) while in subpopulation SAS AF= 0.000414 (2/4826). AF 95% confidence interval is 0.0000787. There are 0 homozygotes in gnomad4. There are 6 alleles in male gnomad4 subpopulation. This position pass quality control queck.
