Single publication in 2012 reported biallelic variants in a consanguineous family and additional heterozygous variants in sporadic patients with cardiac laterality defects. Knockdown nphp4 expression in zebrafish caused laterality defects.
PMID: 22550138; Frenh 2012: Hom missense reported in a consang family with with cardiac laterality defects. 9 additional het sporadic cases reported with features of heterotaxy. p.(Ala1110Val) reported in one patient with abdominal situs inversus but variant is present in gnomAD (1007 hets and 3 hom), another missense, p.(Pro541Leu), reported in patient with midline liver and asplenia (variant is present 228x in gnomAD). Most of the variants in the sporadic cases either many hets or present in homozygosity.
