Genes affected
XYLB (HGNC:12839): (xylulokinase) The protein encoded by this gene shares 22% sequence identity with Hemophilus influenzae xylulokinase, and even higher identity to other gene products in C.elegans (45%) and yeast (31-35%), which are thought to belong to a family of enzymes that include fucokinase, gluconokinase, glycerokinase and xylulokinase. These proteins play important roles in energy metabolism. [provided by RefSeq, Aug 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2023The c.1181C>T (p.T394I) alteration is located in exon 14 (coding exon 14) of the XYLB gene. This alteration results from a C to T substitution at nucleotide position 1181, causing the threonine (T) at amino acid position 394 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
