RELN: BS2 -
The RELN p.Asn1159Lys variant was identified in the literature in two sisters affected with autism (Bonora_2013_PMID:14515139). The variant was identified in dbSNP (ID: rs114684479), LOVD 3.0 and ClinVar (classified as likely benign by GeneDx, Invitae, EGL Genetic Diagnostics and Genetic Services Laboratory, University of Chicago, as uncertain significance by Athena Diagnostics Inc and as pathogenic by Bioinformatics Core, Luxembourg Center for Systems Biomedicine). The variant was identified in control databases in 441 of 282460 chromosomes (2 homozygous) at a frequency of 0.001561 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: Ashkenazi Jewish in 41 of 10358 chromosomes (freq: 0.003958), European (non-Finnish) in 286 of 128856 chromosomes (freq: 0.00222), South Asian in 55 of 30614 chromosomes (freq: 0.001797), Other in 12 of 7208 chromosomes (freq: 0.001665), Latino in 34 of 35392 chromosomes (freq: 0.000961), African in 10 of 24966 chromosomes (freq: 0.000401) and European (Finnish) in 3 of 25122 chromosomes (freq: 0.000119), but was not observed in the East Asian population. The p.Asn1159 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -

Norman-Roberts syndrome Benign:1
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign. -
RELN-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
