Genes affected

C2CD6 (HGNC:14438): (C2 calcium dependent domain containing 6) An autosomal recessive form of juvenile amyotrophic lateral sclerosis was originally mapped to a region of chromosome 2 that includes this gene. The encoded protein contains a calcium-dependent membrane targeting C2 domain. This domain is often found in proteins that are involved in membrane trafficking and signal transduction.

The c.5044G>A (p.A1682T) alteration is located in exon 15 (coding exon 15) of the ALS2CR11 gene. This alteration results from a G to A substitution at nucleotide position 5044, causing the alanine (A) at amino acid position 1682 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
