Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_005045.4(RELN):c.8863C>T(p.Arg2955Cys) variant causes a missense change. The variant allele was found at a frequency of 0.000196 in 1,614,022 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R2955H) has been classified as Uncertain significance.

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: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.05899653).

BP6

Variant 7-103497907-G-A is Benign according to our data. Variant chr7-103497907-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 197982.

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000204 (31/152230) while in subpopulation EAS AF = 0.00366 (19/5188). AF 95% confidence interval is 0.0024. There are 0 homozygotes in GnomAd4. There are 13 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR,AD gene
