Genes affected
NKX6-2 (HGNC:19321): (NK6 homeobox 2) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in cell differentiation; regulation of myelination; and regulation of transcription, DNA-templated. Predicted to act upstream of or within several processes, including negative regulation of transcription by RNA polymerase II; neurogenesis; and neuromuscular process controlling balance. Predicted to be part of chromatin. Predicted to be active in nucleus. Implicated in spastic ataxia 8. [provided by Alliance of Genome Resources, Apr 2022]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 14, 2024The c.682G>A (p.G228S) alteration is located in exon 3 (coding exon 3) of the NKX6-2 gene. This alteration results from a G to A substitution at nucleotide position 682, causing the glycine (G) at amino acid position 228 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
