Candidate Genes for Gluchos1:

Gene	Genome Location (GRCm39)	Reference	QTL Note
Nnt	Chr13:119472063-119545793 (-)	J:109356	Nnt maps to 64 cM on chromosome 13 and was previously identified as a strong candidate gene for Gluchos1. Gluchos1 mapped to 73 cM in an F2 intercross between C57BL/6J (impaired glucose homeostasis) and C3H/HeH (normal glucose homeostasis). C57BL/6J micehave a naturally occurring in-frame deletion of exons 7-11 in Nnt resulting in complete absence of gene product. Transgenic expression of a BAC vector containing a full-length Nnt gene derived from 129S6/SvEvTac in C57BL/6J animals resulted in Nnt protein production levels similar to C3H/HeH and rescue of glucose intolerance and insulin secretion.
