Genes affected

NLGN4Y (HGNC:15529): (neuroligin 4 Y-linked) This gene encodes a type I membrane protein that belongs to the family of neuroligins, which are cell adhesion molecules present at the postsynaptic side of the synapse, and may be essential for the formation of functional synapses. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Mar 2011]

The N401K variant in the NLGN4Y gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The N401K variant was not observed in the Exome Aggregation Consortium (ExAC) data set, indicating it is not a common benign variant (Lek et al., 2016). The N401K variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved in mammals. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret N401K as a variant of uncertain significance. -
