Genes affected

C1QTNF1 (HGNC:14324): (C1q and TNF related 1) Enables collagen binding activity. Involved in several processes, including negative regulation of platelet aggregation; positive regulation of aldosterone secretion; and positive regulation of cytosolic calcium ion concentration. Located in extracellular space. Is integral component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.134C>T (p.S45L) alteration is located in exon 2 (coding exon 1) of the C1QTNF1 gene. This alteration results from a C to T substitution at nucleotide position 134, causing the serine (S) at amino acid position 45 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
