Genes affected
HNF4A (HGNC:5024): (hepatocyte nuclear factor 4 alpha) The protein encoded by this gene is a nuclear transcription factor which binds DNA as a homodimer. The encoded protein controls the expression of several genes, including hepatocyte nuclear factor 1 alpha, a transcription factor which regulates the expression of several hepatic genes. This gene may play a role in development of the liver, kidney, and intestines. Mutations in this gene have been associated with monogenic autosomal dominant non-insulin-dependent diabetes mellitus type I. Alternative splicing of this gene results in multiple transcript variants encoding several different isoforms. [provided by RefSeq, Apr 2012]

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

PM1
In a domain NR LBD (size 230) in uniprot entity HNF4A_HUMAN there are 50 pathogenic changes around while only 3 benign (94%) in NM_175914.5
PP3
MetaRNN computational evidence supports a deleterious effect, 0.949
PP5
Variant 20-44419828-G-A is Pathogenic according to our data. Variant chr20-44419828-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 2574634.Status of the report is no_assertion_criteria_provided, 0 stars.
BS2
High AC in GnomAdExome4 at 10 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
