Monogenic diabetes v2.60 SMPD4 Achchuthan Shanmugasundram Tag Q1_24_promote_green was removed from gene: SMPD4.
Monogenic diabetes v2.60 SMPD4 Achchuthan Shanmugasundram commented on gene: SMPD4: The rating of this gene has been updated to green and the mode of inheritance set to BIALLELIC, autosomal or pseudoautosomal following NHS Genomic Medicine Service approval.
Monogenic diabetes v2.59 SMPD4 Achchuthan Shanmugasundram Source Expert Review Green was added to SMPD4.
Source NHS GMS was added to SMPD4.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Monogenic diabetes v2.57 SMPD4 Achchuthan Shanmugasundram Classified gene: SMPD4 as Amber List (moderate evidence)
Monogenic diabetes v2.57 SMPD4 Achchuthan Shanmugasundram Added comment: Comment on list classification: As reviewed by Dmitrijs Rots, there are five individuals from three unrelated families with biallelic loss-of-function SMPD4 variants. They developed insulin-dependent diabetes, besides presenting with a severe neurodevelopmental disorder and microcephaly. In addition, review of past reports showed 27% of patients had insulin-dependent diabetes.

This gene can therefore be promoted to green rating in the next GMS review.
Monogenic diabetes v2.57 SMPD4 Achchuthan Shanmugasundram Gene: smpd4 has been classified as Amber List (Moderate Evidence).
Monogenic diabetes v2.56 SMPD4 Achchuthan Shanmugasundram Phenotypes for gene: SMPD4 were changed from NDD, microcephaly and diabetes to Neurodevelopmental disorder with microcephaly, arthrogryposis, and structural brain anomalies, OMIM:618622; type 1 diabetes mellitus, MONDO:0005147
Monogenic diabetes v2.55 SMPD4 Achchuthan Shanmugasundram Publications for gene: SMPD4 were set to PMID: 36732302
Monogenic diabetes v2.54 SMPD4 Achchuthan Shanmugasundram Tag Q1_24_promote_green tag was added to gene: SMPD4.
Monogenic diabetes v2.54 SMPD4 Achchuthan Shanmugasundram edited their review of gene: SMPD4: Changed publications to: 36732302
Monogenic diabetes v2.54 SMPD4 Achchuthan Shanmugasundram reviewed gene: SMPD4: Rating: GREEN; Mode of pathogenicity: None; Publications: ; Phenotypes: Neurodevelopmental disorder with microcephaly, arthrogryposis, and structural brain anomalies, OMIM:618622, type 1 diabetes mellitus, MONDO:0005147; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Monogenic diabetes v2.53 SMPD4 Dmitrijs Rots gene: SMPD4 was added
gene: SMPD4 was added to Monogenic diabetes. Sources: Literature
Mode of inheritance for gene: SMPD4 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: SMPD4 were set to PMID: 36732302
Phenotypes for gene: SMPD4 were set to NDD, microcephaly and diabetes
Penetrance for gene: SMPD4 were set to Complete
Review for gene: SMPD4 was set to AMBER
Added comment: PMID: 36732302 reported three independent families with multiple affected individuals with biallelic SMPD4 variants with severe NDD and insulin-dependent diabetes. Given the syndromic presentation - not sure about the relevancy for the panel.
