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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 26, 2022The c.896G>T (p.S299I) alteration is located in exon 7 (coding exon 7) of the SRPX gene. This alteration results from a G to T substitution at nucleotide position 896, causing the serine (S) at amino acid position 299 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
