Genes affected

HAS3 (HGNC:4820): (hyaluronan synthase 3) The protein encoded by this gene is involved in the synthesis of the unbranched glycosaminoglycan hyaluronan, or hyaluronic acid, which is a major constituent of the extracellular matrix. This gene is a member of the NODC/HAS gene family. Compared to the proteins encoded by other members of this gene family, this protein appears to be more of a regulator of hyaluronan synthesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2010]

Ambry Genetics

Nov 29, 2023

The c.113C>T (p.T38M) alteration is located in exon 2 (coding exon 1) of the HAS3 gene. This alteration results from a C to T substitution at nucleotide position 113, causing the threonine (T) at amino acid position 38 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
