Skeletal dysplasia v8.43 PDIA6 Ida Ertmanska changed review comment from: PMID: 35856135 De Franco et al., 2022
Report of a biallelic loss-of-function PDIA6 NM_001282704: p.Val235fs variant in a male proband with polycystic kidney disease, infancy-onset diabetes, and microcephaly. Consanguineous, Middle Eastern parents with history of pregnancy loss.

PMID: 40974269 Al-Hadidi et al., 2026
Report of a full-term male neonate born to consanguineous Syrian parents, who presented with polycystic kidney disease, severe oligohydramnios, pulmonary hypoplasia, microcephaly, rib thoracic dysplasia, and global developmental delay. Homozygous for PDIA6 NM_005742.4 :c.1958delC, p.Pro653fs* variant - cannot find it anywhere, the NM_005742.4 transcript only has 440 amino acids..?

Functional evidence: PMID: 34487921 Chhabra et al., 2023
Mouse model carrying a missense mutation (Phe175Ser) in PDIA6. Homozygous mice were mildly hyperglycemic at weaning and subsequently became hypoinsulinemic and overtly diabetic at the adult stage, due to loss of pancreatic β-cell function and identity.

This conference poster reports 3 cases with PDIA6 variants and polycystic kidney disease with neonatal diabetes. Case 3 homozygous for PDIA6 c.702delT, p.Arg235Glufs*87, other genotypes not stated.; to: PMID: 35856135 De Franco et al., 2022
Report of a biallelic loss-of-function PDIA6 NM_005742:p.Tyr316* variant in a male proband with polycystic kidney disease, infancy-onset diabetes, microcephaly, developmental delay, bilateral sensorineural hearing loss, hypotonia, visual impairment, and steatorrhea. Consanguineous, Middle Eastern parents with history of pregnancy loss.

Skeletal dysplasia v8.43 PDIA6 Ida Ertmanska changed review comment from: Comment on list classification: There are two reports of unrelated individuals with biallelic PDIA6 variants and thoracic dystrophy. However, PMID: 40974269 states the proband harboured a PDIA6 variant p.Pro653fs*, while the gene transcript is 440 amino acids. Hence, this gene can only be rated Amber on Skeletal dysplasia for now.; to: Comment on list classification: There are two reports of unrelated individuals with biallelic PDIA6 variants and thoracic dystrophy.
