Green List (high evidence)

PMID 36197437 Cospain et al 2022 report 11 individuals from 10 families with heterozygous PTC variants in exon 4/4 of the FOSL2 gene. All variants were predicted to escape NMD resulting in a truncated protein, with the truncation occurring proximal to the C-terminal domain (supportive functional studies).

In 10/11 families the variant occurred de novo in a single affected proband. In one family with 2 affected siblings, the variant was present in the siblings but absent in the unaffected parent likely due to gonadal mosaicism.

Clinical features included:
- Cutis aplasia congenital of the scalp (10/11)
- Tooth enamel hypoplasia and discolouration (8/9)
- Multiple other ectodermal features also noted e.g. small brittle nails, hypotrichosis/hypertrichosis, lichen sclerosis
- 5 individuals had cataracts (mostly bilateral, congenital/early childhood onset)
- 6/9 IUGR
- 5/9 postnatal growth restriction
- 7/9 developmental delay/ID
- 5/7 ADHD/ASD
- 2/9 seizures
