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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 20, 2024The c.304T>A (p.S102T) alteration is located in exon 1 (coding exon 1) of the HLX gene. This alteration results from a T to A substitution at nucleotide position 304, causing the serine (S) at amino acid position 102 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
