Genes affected

PHACTR1 (HGNC:20990): (phosphatase and actin regulator 1) The protein encoded by this gene is a member of the phosphatase and actin regulator family of proteins. This family member can bind actin and regulate the reorganization of the actin cytoskeleton. It plays a role in tubule formation and in endothelial cell survival. Polymorphisms in this gene are associated with susceptibility to myocardial infarction, coronary artery disease and cervical artery dissection. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Apr 2016]

TBC1D7-LOC100130357 links:

TBC1D7 (HGNC:21066): (TBC1 domain family member 7) This gene encodes a member of the TBC-domain containing protein family. The encoded protein functions as a subunit of the tuberous sclerosis TSC1-TSC2 complex which plays a role in the regulation of cellular growth and differentiation. Mutations in this gene have been associated with autosomal recessive megalencephaly. Alternative splicing results in multiple transcript variants. Naturally occurring readthrough transcription occurs between this locus and downstream LOC100130357. [provided by RefSeq, Jan 2016]

The c.1688C>G (p.T563S) alteration is located in exon 14 (coding exon 12) of the PHACTR1 gene. This alteration results from a C to G substitution at nucleotide position 1688, causing the threonine (T) at amino acid position 563 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
