Genes affected

BASP1 (HGNC:957): (brain abundant membrane attached signal protein 1) This gene encodes a membrane bound protein with several transient phosphorylation sites and PEST motifs. Conservation of proteins with PEST sequences among different species supports their functional significance. PEST sequences typically occur in proteins with high turnover rates. Immunological characteristics of this protein are species specific. This protein also undergoes N-terminal myristoylation. Alternative splicing results in multiple transcript variants that encode the same protein. [provided by RefSeq, Oct 2012]

Ambry Genetics

Nov 29, 2023

The c.446A>G (p.K149R) alteration is located in exon 2 (coding exon 1) of the BASP1 gene. This alteration results from a A to G substitution at nucleotide position 446, causing the lysine (K) at amino acid position 149 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
