Genes affected
HMGN1 (HGNC:4984): (high mobility group nucleosome binding domain 1) The protein encoded by this gene binds nucleosomal DNA and is associated with transcriptionally active chromatin. Along with a similar protein, HMG17, the encoded protein may help maintain an open chromatin configuration around transcribable genes. [provided by RefSeq, Aug 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2021The c.190G>A (p.E64K) alteration is located in exon 5 (coding exon 5) of the HMGN1 gene. This alteration results from a G to A substitution at nucleotide position 190, causing the glutamic acid (E) at amino acid position 64 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
