Genes affected

PPFIBP2 (HGNC:9250): (PPFIA binding protein 2) This gene encodes a member of the LAR protein-tyrosine phosphatase-interacting protein (liprin) family. The encoded protein is a beta liprin and plays a role in axon guidance and neuronal synapse development by recruiting LAR protein-tyrosine phosphatases to the plasma membrane. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Feb 2012]

Collection Method: clinical testing

The c.182T>C (p.L61S) alteration is located in exon 3 (coding exon 2) of the PPFIBP2 gene. This alteration results from a T to C substitution at nucleotide position 182, causing the leucine (L) at amino acid position 61 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
