Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_006307.5(SRPX):​c.1238C>T​(p.Ser413Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0707 in 1,203,841 control chromosomes in the GnomAD database, including 2,529 homozygotes. There are 26,479 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt.

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.008332968).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.0776 is higher than 0.05.
