Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 1P and 5B. PP2BP4_StrongBS1_Supporting

The NM_005045.4(RELN):c.10016T>C(p.Met3339Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000359 in 1,613,936 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict 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. M3339L) 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 made for transcript

Verdict is Likely_benign. Variant got -4 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=0.03701806).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000164 (25/152262) while in subpopulation AFR AF= 0.000579 (24/41472). AF 95% confidence interval is 0.000399. There are 0 homozygotes in gnomad4. There are 11 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
