Genes affected

PPFIA3 (HGNC:9247): (PTPRF interacting protein alpha 3) The protein encoded by this gene is a member of the LAR protein-tyrosine phosphatase-interacting protein (liprin) family. Liprins interact with members of LAR family of transmembrane protein tyrosine phosphatases, which are known to be important for axon guidance and mammary gland development. Liprin family protein has been shown to localize phosphatase LAR to cell focal adhesions and may be involved in the molecular organization of presynaptic active zones. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 28, 2023

The c.645T>G (p.D215E) alteration is located in exon 6 (coding exon 5) of the PPFIA3 gene. This alteration results from a T to G substitution at nucleotide position 645, causing the aspartic acid (D) at amino acid position 215 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
