Genes affected

HLX (HGNC:4978): (H2.0 like homeobox) Enables sequence-specific DNA binding activity. Predicted to be involved in cell differentiation and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including animal organ development; enteric nervous system development; and regulation of T-helper cell differentiation. Predicted to be located in nucleus. Predicted to be part of chromatin. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0012665093).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.147 is higher than 0.05.
