Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4BS1_Supporting

The NM_005045.4(RELN):c.7634C>T(p.Ala2545Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000322 in 1,614,048 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. A2545A) has been classified as Likely benign.

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 was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.27547157).

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000145 (22/152158) while in subpopulation NFE AF = 0.000206 (14/68000). AF 95% confidence interval is 0.000124. There are 0 homozygotes in GnomAd4. There are 11 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Reported previously in an individual with autism spectrum disorder; however, a missense variant in another gene was also identified in this individual and no further clinical information was provided (Varga et al., 2017); Reported previously in an individual with autism spectrum disorder who had a second RELN variant on the opposite chromosome (in trans) (M Sanchez-Sanchez et al., 2018); however we consider the second RELN variant identified to be benign; In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 29969175, 28677532, 34426522, 32060413, 31623367, 35668055) -

Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is higher than would generally be expected for pathogenic variants in this gene. (http://gnomad.broadinstitute.org) Polyphen and MutationTaster yielded discordant predictions regarding whether this amino acid change is damaging to the protein. -
