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.5141T>C (p.L1714P) alteration is located in exon 15 (coding exon 15) of the ALS2CR11 gene. This alteration results from a T to C substitution at nucleotide position 5141, causing the leucine (L) at amino acid position 1714 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
