Genes affected

FCHSD2 (HGNC:29114): (FCH and double SH3 domains 2) Enables phosphatidylinositol-3,4,5-trisphosphate binding activity and phosphatidylinositol-3,4-bisphosphate binding activity. Involved in clathrin-dependent endocytosis and positive regulation of Arp2/3 complex-mediated actin nucleation. Located in plasma membrane. Colocalizes with clathrin-coated pit.

The c.2011G>A (p.D671N) alteration is located in exon 18 (coding exon 18) of the FCHSD2 gene. This alteration results from a G to A substitution at nucleotide position 2011, causing the aspartic acid (D) at amino acid position 671 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
