Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 7P and 1B. PM5PP3_StrongPP5BS2_Supporting

The NM_175914.5(HNF4A):​c.778G>A​(p.Asp260Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000684 in 1,461,868 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D260Y) has been classified as Likely pathogenic.

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 was made for transcript

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

PM5
Other missense variant is known to change same aminoacid residue: Variant chr20-44419828-G-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 549555.Status of the report is reviewed_by_expert_panel, 3 stars.
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 VariationId 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.
