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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RELN. . Gene score misZ 2.2497 (greater than the threshold 3.09). Trascript score misZ 4.2638 (greater than threshold 3.09). GenCC has associacion of gene with ankylosing spondylitis, lissencephaly with cerebellar hypoplasia, Norman-Roberts syndrome, complex neurodevelopmental disorder, autosomal dominant epilepsy with auditory features, familial temporal lobe epilepsy 7.

BP4

Computational evidence support a benign effect (MetaRNN=0.010646611).

BP6

Variant 7-103539296-G-A is Benign according to our data. Variant chr7-103539296-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 475979.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}. Variant chr7-103539296-G-A is described in Lovd as [Likely_benign].

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000341 (52/152280) while in subpopulation EAS AF= 0.00771 (40/5188). AF 95% confidence interval is 0.00582.
