Severe microcephaly v2.286 AP4E1 Eleanor Williams Tag for-review was removed from gene: AP4E1.
Severe microcephaly v2.282 AP4E1 Sarah Leigh commented on gene: AP4E1
Severe microcephaly v2.281 AP4E1 Eleanor Williams Source Expert Review Green was added to AP4E1.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Severe microcephaly v2.87 AP4E1 Arina Puzriakova changed review comment from: Comment on list classification: New gene added by Zornitza Stark. Rating Amber but there is sufficient evidence to rate Green at the next GMS panel update (added 'for-review' tag)

At least 21 individuals from 11 unrelated families reported in literature with variants in this gene (PMID: 32979048). Microcephaly was observed in 14/16 cases but details regarding head circumference were mostly unavailable. At least 5 individuals (2 families) had microcephaly of relevant severity to this panel (OFC ≤ -3 SD) (see PMIDs: 21620353 and 20972249).; to: Comment on list classification: New gene added by Zornitza Stark. Rating Amber with recommendation of review by the GMS team to assess whether there is sufficient evidence to support a Green rating (added 'for-review' tag)

At least 21 individuals from 11 unrelated families reported in literature with variants in this gene (PMID: 32979048). Microcephaly was observed in 14/16 cases but precise details regarding head circumference were mostly omitted (no relevant info was provided for the remaining 5 patients). However, at least 5 individuals (2 families) had microcephaly of relevant severity to this panel (OFC ≤ -3 SD) (see PMIDs: 21620353 and 20972249).
Severe microcephaly v2.65 AP4E1 Arina Puzriakova Publications for gene: AP4E1 were set to 20972249; 21620353; 21937992
Severe microcephaly v2.64 AP4E1 Arina Puzriakova Tag for-review tag was added to gene: AP4E1.
Severe microcephaly v2.64 AP4E1 Arina Puzriakova Classified gene: AP4E1 as Amber List (moderate evidence)
