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]

RELN (HGNC:):

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.53).
• BP6: Variant 7-103539319-A-G is Benign according to our data. Variant chr7-103539319-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 212044.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=3, Uncertain_significance=2}. Variant chr7-103539319-A-G is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=-0.048 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000571 (87/152358) while in subpopulation AFR AF= 0.00197 (82/41588). AF 95% confidence interval is 0.00163. There are 1 homozygotes in gnomad4. There are 49 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAdExome4 at 2 AD,AR gene
