The API c.174G>C (p.Lys58Asn) missense variant has been reported in at least two studies in which it is found in two patients with pituitary macroadenoma in a heterozygous state (Tichomirowa et al. 2011; Cazabat L. 2012). The p.Lys58Asn variant was absent from 360 controls but is reported at a frequency of 0.00003 in the European (non-Finnish) population of the Exome Aggregation Consortium, though this is based on only two alleles but in a region of good sequence coverage. Based on the limited evidence, p.Lys58Asn variant is classified as a variant of uncertain significance but suspicious for pathogenicity for familial isolated pituitary adenomas. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.
