Deep‐Intronic Variant in RUNX2 Causing Pseudo‐Exon Inclusion in a Family With Cleidocranial Dysplasia

Clinical Genetics, EarlyView.
A deep‐intronic single nucleotide variant in RUNX2 causes the characteristic clinical features of cleidocranial dysplasia (CCD) in a family via pseudo‐exon inclusion into the mRNA. The pseudo‐exon contains a premature stop codon and triggers mRNA decay, which results in RUNX2 haploinsufficiency, the known disease mechanism.

GAPO Syndrome – Diagnosis of a Rare Case Report and Review

Journal of Indian Academy of Oral Medicine and Radiology
GAPO syndrome is an unusual genetic disorder with an autosomal recessive trait inheritance. The syndrome is caused due a genetic defect or alterations in the ANTXR1/TEM8 gene.

Novel Postzygotic Variants Associated With Hypomelanosis of Ito Expand the ACTB‐Related Neurocutaneous Disease Spectrum

Clinical Genetics, EarlyView.
We describe a previously unreported phenotype related to postzygotic ACTB variants with hypomelanosis of Ito, characterized by hypopigmentation associated or not with neurodevelopmental features, distinct from Becker presentations, bridging constitutional neurodevelopmental and somatic cutaneous phenotypes.

Goldenhar syndrome with blepharophimosis and limb deformities: a case report

BMC Ophthalmology, 2018
Background Goldenhar syndrome has variable presentations and can affect multiple regions of the body. Diagnoses are based on clinical manifestations. The association of Goldenhar syndrome with blepharophimosis and limb deformities has not previously been

USP34 Haploinsufficiency as a Cause of Neurodevelopmental Phenotypes

Clinical Genetics, EarlyView.
Heterozygous loss‐of‐function variants in USP34 cause a novel neurodevelopmental disorder characterized by global developmental delay, speech impairment, autism, hypotonia, craniofacial dysmorphism, and distal limb anomalies. Disrupted Wnt/β‐catenin signaling via reduced Axin stabilization refines gene‐specific contributions within 2p15p16.1 ...

Report of trisomy 2q34-qter and monosomy 4q35.2-qter in a child with mild dysmorphic syndrome and karyotype 46,XY,der(4)t(2;4)(q34;q35.2)pat

Molecular Cytogenetics, 2020
Background Concomitant trisomy 2q3 and monosomy 4q3 have been rarely reported. Pure trisomy 2q3 has been associated with microcephaly, hypertelorism, low-set ears, micrognathia, visceral abnormalities, and growth retardation. Monosomy 4q3 includes a wide

Cutis Tricolor‐Like Pigmentary Mosaicism in Mowat–Wilson Syndrome: Phenotypic Overlap With Ruggieri–Happle Syndrome

Pediatric Dermatology, EarlyView.
ABSTRACT Cutis tricolor (CT) is a rare pigmentary mosaicism characterized by the coexistence of hyperpigmented and hypopigmented areas on a background of normal skin; its syndromic form, Ruggieri–Happle syndrome (RHS), is associated with neurodevelopmental delay, facial dysmorphism, skeletal abnormalities, and other systemic defects.

Holoprosencephaly, hypertelorism, and ectrodactyly in a boy with an apparently balanced de novo t(2;4)(q14.2;q35)

, 2000
A holoprosencephaly, hypertelorism, and ectrodactyly syndrome (HHES) was described in three previous cases in whom chromosomes were apparently normal. We report on a 3-year-old boy with HHES and a de novo apparently balanced t(2;4)(q14.2;q35) confirmed ...

Optimizing Diagnostic Accuracy of Clinical Red Flags in RASopathies

American Journal of Medical Genetics Part A, Volume 200, Issue 7, Page 1608-1618, July 2026.
ABSTRACT RASopathies are a group of genetic disorders caused by pathogenic variants in the RAS‐mitogen‐activated protein kinase (RAS–MAPK) signaling pathway, often presenting with congenital heart defects, craniofacial dysmorphisms, and developmental delays. To assess the diagnostic yield of genetic testing in patients with suspected RASopathies and to

The Hypertelorism-Hypospadias (BBB) Syndrome: Endocrine Evaluation in Two Prepubertal Siblings

, 1989
We studied two male siblings with the hypertelorism-hypospadias syndrome, and investigated the role of the hypothalamic-hypophyseal-gonadal axis in the pathogenesis of the hypospadias. The absence of evident endocrine abnormalities led us to suppose that
