Genes affected

NEURL2 (HGNC:16156): (neuralized E3 ubiquitin protein ligase 2) This gene encodes a protein that is involved in the regulation of myofibril organization. This protein is likely the adaptor component of the E3 ubiquitin ligase complex in striated muscle, and it regulates the ubiquitin-mediated degradation of beta-catenin during myogenesis. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jun 2013]

NEURL2 links:

CTSA (HGNC:9251): (cathepsin A) This gene encodes a member of the peptidase S10 family of serine carboxypeptidases. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate two chains that comprise the heterodimeric active enzyme. This enzyme possesses deamidase, esterase and carboxypeptidase activities and acts as a scaffold in the lysosomal multienzyme complex. Mutations in this gene are associated with galactosialidosis.

SPATA25 (HGNC:16158): (spermatogenesis associated 25) Involved in spermatogenesis. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.391G>A (p.E131K) alteration is located in exon 1 (coding exon 1) of the NEURL2 gene. This alteration results from a G to A substitution at nucleotide position 391, causing the glutamic acid (E) at amino acid position 131 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
