Genes affected

ADD1 (HGNC:243): (adducin 1) Adducins are a family of cytoskeletal proteins encoded by three genes (alpha, beta, and gamma). Adducin acts as a heterodimer of the related alpha, beta, or gamma subunits. The protein encoded by this gene represents the alpha subunit. Alpha- and beta-adducin include a protease-resistant N-terminal region and a protease-sensitive, hydrophilic C-terminal region. Adducin binds with high affinity to Ca(2+)/calmodulin and is a substrate for protein kinases A and C. [provided by RefSeq, Aug 2017]

Ambry Genetics

Sep 29, 2023

The c.928A>T (p.S310C) alteration is located in exon 8 (coding exon 7) of the ADD1 gene. This alteration results from a A to T substitution at nucleotide position 928, causing the serine (S) at amino acid position 310 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
