Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.
The NM_005045.4(RELN):c.5005A>C(p.Ser1669Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000062 in 1,613,786 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S1669T) has been classified as Likely benign.

Inborn genetic diseases Uncertain:1
The c.5005A>C (p.S1669R) alteration is located in exon 34 (coding exon 34) of the RELN gene. This alteration results from a A to C substitution at nucleotide position 5005, causing the serine (S) at amino acid position 1669 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
Norman-Roberts syndrome;C4225327:Familial temporal lobe epilepsy 7 Uncertain:1
This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 1669 of the RELN protein (p.Ser1669Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RELN-related conditions. ClinVar contains an entry for this variant (Variation ID: 542571). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RELN protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
