Genetic Variant GSX2:p.His124Asp (chr4-54100714-C-G) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_133267.3(GSX2):c.370C>G(p.His124Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000194 in 1,548,740 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H124N) has been classified as Uncertain significance.

Genes affected

GSX2 (HGNC:24959): (GS homeobox 2) Enables DNA-binding transcription factor activity, RNA polymerase II-specific and sequence-specific double-stranded DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including nervous system development; positive regulation of Notch signaling pathway; and regulation of respiratory gaseous exchange by nervous system process. Located in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]
