| Severe microcephaly v9.13 | VPS36 | Ida Ertmanska Classified gene: VPS36 as Amber List (moderate evidence) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Severe microcephaly v9.13 | VPS36 | Ida Ertmanska Added comment: Comment on list classification: While there are 3 unrelated pedigrees reported in literature with biallelic VPS36 variants and microcephaly, the severity of microcephaly is not stated. Hence, it is unclear whether this association fits into the scope of the Severe microcephaly panel. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Severe microcephaly v9.13 | VPS36 | Ida Ertmanska Gene: vps36 has been classified as Amber List (Moderate Evidence). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Severe microcephaly v9.12 | VPS36 |
Ida Ertmanska changed review comment from: PMID: 42362802 Chaurasia et al., 2026 Family 21 - VPS36 exon2-3 deletion - 3 affected sibs, one deceased (8yrs) Family 51 - consanguineous parents; VPS36 c.1103G>A, p.Arg368His - 2 affected sibs, died at 15 months and 3 years Family 52 - consanguineous parents; VPS36 c.1103G>A, p.Arg368His - 2 affected sibs, died at 4 months and 21 months Family 53 - consanguineous parents; VPS36 c.1103G>A, p.Arg368His - 3 affected sibs, deceased; 2 unaffected sibs not genotyped Probands confirmed homozygous, unaffected parents heterozygous. Families 51-53 = 2 Pakistani and 1 Saudi Arabian family. F51 and F53 (Pakistani) were found to have common ancestry, but F52 had a different haplotype. Phenotypic spectrum of 6 genotyped affected individuals: microcephaly (5/6), motor & speech delay (6/6), ID (5/5 assessed), seizures (5/6), spasticity (5/5), CC agenesis (6/6), cerebellar atrophy (4/6), ventriculomegaly (5/5). PMID: 28600779 Monies et al., 2017 Individual 16W-0233 - Saudi Arabian patient, homozygous for VPS36:NM_001282169:exon14:c.894-2->T - phenotype: Speech delay, intellectual disability.
