Monogenic Diabetes VCEP

The c.361A>G variant in the hepatocyte nuclear factor-4 alpha gene, HNF4A, causes an amino acid change of serine to glycine at codon 121 (p.(Ser121Gly)) in NM_175914.5. The Popmax filtering allele frequency of the c.361A>G variant in gnomAD v2.1.1 is 0.00006673, which is greater than the MDEP threshold for BS1 (0.000033) (BS1). This variant has a REVEL score of 0.555, which is between the ClinGen MDEP established cutoffs for PP3 and BS4, predicting neither a damaging nor benign impact on HNF4A function; thus, neither criterion will be applied. This variant was identified in a patient with an alternate molecular basis for disease (BP5; internal lab contributors). In summary, c.361A>G meets the criteria to be classified as likely benign for monogenic diabetes. ACMG/AMP criteria applied, as specified by the ClinGen MDEP VCEP (specification version 1.0.0, approved 11/16/2022): BS1, BP5.

BS1

The Popmax filtering allele frequency of the c.361A>G variant in gnomAD v2.1.1 is 0.00006673, which is greater than the MDEP threshold for BS1 (0.000033) (BS1).

BP5

This variant was identified in a patient with an alternate molecular basis for disease (BP5; internal lab contributors).

PP3

This variant has a REVEL score of 0.555, which is between the ClinGen MDEP established cutoffs for PP3 and BS4, predicting neither a damaging nor benign impact on HNF4A function; thus, neither criterion will be applied.
