Genes affected

SRPX (HGNC:11309): (sushi repeat containing protein X-linked) Predicted to be an extracellular matrix structural constituent. Predicted to be involved in cell adhesion. Predicted to act upstream of or within several processes, including negative regulation of cell proliferation involved in contact inhibition; phagolysosome assembly; and positive regulation of extrinsic apoptotic signaling pathway in absence of ligand. Part of collagen-containing extracellular matrix. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.1111C>T (p.L371F) alteration is located in exon 9 (coding exon 9) of the SRPX gene. This alteration results from a C to T substitution at nucleotide position 1111, causing the leucine (L) at amino acid position 371 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
