Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.194G>A (p.R65H) alteration is located in exon 2 (coding exon 2) of the HS3ST5 gene. This alteration results from a G to A substitution at nucleotide position 194, causing the arginine (R) at amino acid position 65 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
