Fetal anomalies v1.973 TBC1D32 Sarah Leigh Publications for gene: TBC1D32 were set to 32573025; 31130284; 32060556
Fetal anomalies v1.860 TBC1D32 Eleanor Williams Tag gene-checked tag was added to gene: TBC1D32.
Fetal anomalies v1.836 TBC1D32 Arina Puzriakova Tag for-review was removed from gene: TBC1D32.
Fetal anomalies v1.836 TBC1D32 Arina Puzriakova commented on gene: TBC1D32: The rating of this gene has been updated following NHS Genomic Medicine Service approval.
Fetal anomalies v1.835 TBC1D32 Arina Puzriakova Source Expert Review Green was added to TBC1D32.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Fetal anomalies v1.558 TBC1D32 Arina Puzriakova Classified gene: TBC1D32 as Amber List (moderate evidence)
Fetal anomalies v1.558 TBC1D32 Arina Puzriakova Added comment: Comment on list classification: New gene added by Rhiannon Mellis (GOSH). There are sufficient unrelated cases with a fetally-relevant phenotype and biallelic variants in TBC1D32 to promoted this gene to Green at the next GMS panel update (added 'for-review' tag)
Fetal anomalies v1.558 TBC1D32 Arina Puzriakova Gene: tbc1d32 has been classified as Amber List (Moderate Evidence).

Fetal anomalies v1.185 TBC1D32 Rhiannon Mellis gene: TBC1D32 was added
gene: TBC1D32 was added to Fetal anomalies. Sources: Literature
Mode of inheritance for gene: TBC1D32 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: TBC1D32 were set to PMID: 32573025; 31130284; 32060556
Phenotypes for gene: TBC1D32 were set to OFD IX
Review for gene: TBC1D32 was set to GREEN
Added comment: Now 5 families reported:

The same group who reported the first individual with a ciliopathy phenotype (Adly et al 2014) now report two further unrelated fetal cases (Alsahan 2020, Monies et al 2019) with OFD/ciliopathy phenotype:

- One had polyhydramnios, hydrocephaly with enlarged biparietal diameter and dilated lateral ventricles, single nostril, anophthalmia, short long bones and echogenic lungs
- The other had holoprosencephaly, cyclops, cleft lip, ventricular septal defect, agenesis of corpus callosum, and club feet

- There are also two sib pairs (one Finnish, one Pakistani) reported by Hietamaki et al 2020 with TBC1D32 variants and a variable phenotype of pituitary hypoplasia +/- other midline defects, hydrocephalus, short limbs, polydactyly
