Genes affected

CASS4 (HGNC:15878): (Cas scaffold protein family member 4) Enables protein tyrosine kinase binding activity. Involved in several processes, including positive regulation of protein kinase B signaling; positive regulation of protein tyrosine kinase activity; and positive regulation of substrate adhesion-dependent cell spreading. Located in focal adhesion. Part of cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The c.773C>T (p.T258M) alteration is located in exon 6 (coding exon 5) of the CASS4 gene. This alteration results from a C to T substitution at nucleotide position 773, causing the threonine (T) at amino acid position 258 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
