Genes affected
ST6GALNAC6 (HGNC:23364): (ST6 N-acetylgalactosaminide alpha-2,6-sialyltransferase 6) ST6GALNAC6 belongs to a family of sialyltransferases that modify proteins and ceramides on the cell surface to alter cell-cell or cell-extracellular matrix interactions (Tsuchida et al., 2003 [PubMed 12668675]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2024The c.124C>T (p.R42W) alteration is located in exon 4 (coding exon 3) of the ST6GALNAC6 gene. This alteration results from a C to T substitution at nucleotide position 124, causing the arginine (R) at amino acid position 42 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
