Severe microcephaly v2.287 MORC2 Eleanor Williams Tag for-review was removed from gene: MORC2.
Severe microcephaly v2.282 MORC2 Sarah Leigh commented on gene: MORC2
Severe microcephaly v2.281 MORC2 Eleanor Williams Source Expert Review Green was added to MORC2.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Severe microcephaly v2.51 MORC2 Arina Puzriakova Classified gene: MORC2 as Amber List (moderate evidence)
Severe microcephaly v2.51 MORC2 Arina Puzriakova Added comment: Comment on list classification: Though signs suggestive of neuropathy were observed in the cohort presented by Sacoto et al (PMID:32693025), these were not the predominant feature of the disease presentation or the primary indication for diagnostic testing. Inclusion on this panel would be of value for detecting such cases, and so this gene should be promoted to Green at the next GMS panel update (added 'for-review' tag)
Severe microcephaly v2.51 MORC2 Arina Puzriakova Gene: morc2 has been classified as Amber List (Moderate Evidence).
Severe microcephaly v2.50 MORC2 Arina Puzriakova gene: MORC2 was added
gene: MORC2 was added to Severe microcephaly. Sources: Literature
for-review tags were added to gene: MORC2.
Mode of inheritance for gene: MORC2 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Publications for gene: MORC2 were set to 32693025
Phenotypes for gene: MORC2 were set to Developmental delay; Intellectual disability; Growth retardation; Microcephaly; Craniofacial dysmorphism; Charcot-Marie-Tooth disease, axonal, type 2Z, OMIM:616688
Review for gene: MORC2 was set to GREEN
Added comment: MORC2 variants have commonly been associated with CMT, presenting axonal neuropathy with progressive weakness, muscle cramps and sensory impairment. However, Sacoto et al (2020) (PMID: 32693025) present a cohort of 20 individuals (19 kindreds) with a neurodevelopmental disorder characterised by DD, ID (18/20 - mild to severe), short stature (18/20), microcephaly (15/20) and variable craniofacial dysmorphisms. Severity of microcephaly relevant to this panel (≥ 3 SD) was observed in 7 subjects.
