Source NHS GMS was added to ARPC4.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Severe microcephaly v4.17 ARPC4 Achchuthan Shanmugasundram Tag Q2_23_promote_green tag was added to gene: ARPC4.
Severe microcephaly v4.17 ARPC4 Achchuthan Shanmugasundram Classified gene: ARPC4 as Amber List (moderate evidence)
Severe microcephaly v4.17 ARPC4 Achchuthan Shanmugasundram Added comment: Comment on list classification: There is sufficient evidence for this gene to be rated GREEN at the next GMS review.
Severe microcephaly v4.17 ARPC4 Achchuthan Shanmugasundram Gene: arpc4 has been classified as Amber List (Moderate Evidence).
Severe microcephaly v4.16 ARPC4 Achchuthan Shanmugasundram Phenotypes for gene: ARPC4 were changed from Microcephaly; mild motor delays; significant speech impairment to Developmental delay, language impairment, and ocular abnormalities, OMIM:620141; microcephaly, MONDO:0001149
Severe microcephaly v4.15 ARPC4 Achchuthan Shanmugasundram Publications for gene: ARPC4 were set to DOI:https://doi.org/10.1016/j.xhgg.2021.100072
Severe microcephaly v4.14 ARPC4 Achchuthan Shanmugasundram commented on gene: ARPC4: As reviewed by Zornitza Stark, PMID:35047857 reported seven cases from six unrelated families with the same missense variant (p.Arg158Cys) and presenting with developmental and speech delays, of which six individuals from five families presented with microcephaly. Three individuals from two of these families had severe microcephaly with occipitofrontal circumference (OFC) beyond 3 standard deviations below the mean for age. In addition, functional studies showed that the variant is associated with a decreased amount of F-actin in cells from two affected individuals.

This gene has been associated with relevant phenotypes in both OMIM (MIM #620141) and Gene2Phenotype (ARPC4-related microcephaly and developmental delay with 'strong' rating in the DD panel).

Added comment: 7 affected individuals from 6 families (gonadal mosaicism was confirmed in the mother of the 2 affected siblings) with a recurrent missense variant (NM_005718.4:c.472C>T; p.R158C). 6/7 affected individuals had microcephaly. The variant was associated with a decreased amount of F-actin in cells from two affected individuals.
