The results for the HFE gene contain the types of mutations that are specified in <xr id="hgmd"/>:

**Table 1:** Table of the different mutation types that were found for HFE in the HGMD.
mutation type	definition	number
missense, nonsense	mutation that leads to a change of amino acid or a stop codon	28
splicing	mutation that affects mRNA splicing	3
regulatory	substitiution causing abnormal regulation	1
small deletion	micro deletion (<= 20 bp)	4
small insertion	micro insertions (<= 20 bp)	1
small indel	micro indels (<= 20 bp)	0
gross deletion	delition > 20 bp	2
gross insertions/duplications	insertion > 20bp	0
complex rearrangments	rearrangements of stretches of the DNA sequence	1
repeat variations	differences in repeat length	0
