Genes affected

GDAP1 (HGNC:15968): (ganglioside induced differentiation associated protein 1) This gene encodes a member of the ganglioside-induced differentiation-associated protein family, which may play a role in a signal transduction pathway during neuronal development. Mutations in this gene have been associated with various forms of Charcot-Marie-Tooth Disease and neuropathy. Two transcript variants encoding different isoforms and a noncoding variant have been identified for this gene. [provided by RefSeq, Feb 2012]

The S11R variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The S11R variant is observed in 134/34386 (0.4%) alleles from individuals of Latino background (Lek et al., 2016). The S11R variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. However, in-silico analyses, including protein predictors and evolutionary conservation, support that this variant does not alter protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -
