Genes affected

LINGO1 (HGNC:21205): (leucine rich repeat and Ig domain containing 1) Predicted to enable epidermal growth factor receptor binding activity. Predicted to act upstream of or within generation of neurons and protein kinase B signaling. Predicted to be located in plasma membrane. Predicted to be active in extracellular matrix and extracellular space. Implicated in autosomal recessive non-syndromic intellectual disability and glaucoma.

The c.1565C>T (p.P522L) alteration is located in exon 2 (coding exon 2) of the LINGO1 gene. This alteration results from a C to T substitution at nucleotide position 1565, causing the proline (P) at amino acid position 522 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
