Genes affected

SCAF8 (HGNC:20959): (SR-related CTD associated factor 8) Enables RNA binding activity and RNA polymerase II C-terminal domain phosphoserine binding activity. Involved in negative regulation of termination of RNA polymerase II transcription, poly(A)-coupled and positive regulation of DNA-templated transcription, elongation. Located in nucleoplasm.

SCAF8 links:

TIAM2 (HGNC:11806): (TIAM Rac1 associated GEF 2) This gene encodes a guanine nucleotide exchange factor. A highly similar mouse protein specifically activates ras-related C3 botulinum substrate 1, converting this Rho-like guanosine triphosphatase (GTPase) from a guanosine diphosphate-bound inactive state to a guanosine triphosphate-bound active state. The encoded protein may play a role in neural cell development. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

The c.3664C>T (p.H1222Y) alteration is located in exon 20 (coding exon 20) of the SCAF8 gene. This alteration results from a C to T substitution at nucleotide position 3664, causing the histidine (H) at amino acid position 1222 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
