Genes affected
INA (HGNC:6057): (internexin neuronal intermediate filament protein alpha) Neurofilaments are type IV intermediate filament heteropolymers composed of light, medium, and heavy chains. Neurofilaments comprise the axoskeleton and they functionally maintain the neuronal caliber. They may also play a role in intracellular transport to axons and dendrites. This gene is a member of the intermediate filament family and is involved in the morphogenesis of neurons. [provided by RefSeq, Jun 2009]
NT5C2 (HGNC:8022): (5'-nucleotidase, cytosolic II) This gene encodes a hydrolase that serves as an important role in cellular purine metabolism by acting primarily on inosine 5'-monophosphate and other purine nucleotides. [provided by RefSeq, Oct 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 18, 2024The c.157G>T (p.A53S) alteration is located in exon 1 (coding exon 1) of the INA gene. This alteration results from a G to T substitution at nucleotide position 157, causing the alanine (A) at amino acid position 53 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
