Variant chr10-132784972-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_177400.3(NKX6-2):c.778C>T(p.Pro260Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000018 in 1,612,736 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. P260P) has been classified as Likely benign.

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]
