Collection Method: clinical testing

The c.329A>G (p.K110R) alteration is located in exon 3 (coding exon 3) of the THEM5 gene. This alteration results from a A to G substitution at nucleotide position 329, causing the lysine (K) at amino acid position 110 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
