Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4_ModerateBP6BS1

The NM_005045.4(RELN):​c.6166C>T​(p.Pro2056Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000725 in 1,614,108 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). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P2056T) 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 -7 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.20203462).
BP6
Variant 7-103551203-G-A is Benign according to our data. Variant chr7-103551203-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 542578.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000355 (54/152282) while in subpopulation AFR AF = 0.00123 (51/41548). AF 95% confidence interval is 0.000958. There are 0 homozygotes in GnomAd4. There are 26 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.6166C>T (p.P2056S) alteration is located in exon 41 (coding exon 41) of the RELN gene. This alteration results from a C to T substitution at nucleotide position 6166, causing the proline (P) at amino acid position 2056 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
