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.79G>A (p.A27T) alteration is located in exon 3 (coding exon 2) of the PPFIBP2 gene. This alteration results from a G to A substitution at nucleotide position 79, causing the alanine (A) at amino acid position 27 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
