Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2 PP2 BP4_Moderate

The NM_005045.4(RELN):​c.6193G>C​(p.Val2065Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• 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=0.07685962).
