Genes affected

PPFIA1 (HGNC:9245): (PTPRF interacting protein alpha 1) 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. This protein binds to the intracellular membrane-distal phosphatase domain of tyrosine phosphatase LAR, and appears to localize LAR to cell focal adhesions. This interaction may regulate the disassembly of focal adhesion and thus help orchestrate cell-matrix interactions. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 27, 2023

The c.64C>T (p.H22Y) alteration is located in exon 2 (coding exon 1) of the PPFIA1 gene. This alteration results from a C to T substitution at nucleotide position 64, causing the histidine (H) at amino acid position 22 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
