| Mendeliome v1.1327 | AXIN1 |
Zornitza Stark edited their review of gene: AXIN1: Added comment: PMID: 37582359 - four families (7 individuals) with three homozygous truncating variants. - all variant shown to result in reduced protein, though 1/3 would be NMD predicted - Probands had macrocephaly (4/6), GDD (3/7), hip dysplasia (5/6), cardiac anomalies eg. VSD/ASD (3/7), cranial hyperostosis and vertebral endplate sclerosis; Changed rating: GREEN; Changed publications: 37582359; Changed phenotypes: Craniometadiaphyseal osteosclerosis with hip dysplasia, MIM# 620558; Changed mode of inheritance: BIALLELIC, autosomal or pseudoautosomal |

| Mendeliome v1.601 | TRPC5 |
Hazel Phillimore gene: TRPC5 was added gene: TRPC5 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: TRPC5 was set to X-LINKED: hemizygous mutation in males, biallelic mutations in females Publications for gene: TRPC5 were set to PMID: 36323681; 24817631; 23033978; 33504798; 28191890 Phenotypes for gene: TRPC5 were set to Intellectual disability; autistic spectrum disorder Review for gene: TRPC5 was set to AMBER Added comment: PMID: 36323681; Leitão E. et al. (2022) Nat Commun.13(1):6570: Missense variant NM_012471.2:c.523C>T, p.(Arg175Cys in three brothers with intellectual disability (ID) and autistic spectrum disorder (ASD), inherited from an asymptomatic mother and absent in the maternal grandparents. Whole cell patch clamp studies of HEK293 created by site-directed mutagenesis showed increased current of this calcium channel (constitutively opened). (This variant is absent in gnomAD v2.1.1). Also, the nonsense variant, c.965G> A, p.(Trp322*) was found in a high functioning ASD male (maternally inherited), NMD-predicted. Other papers and TRPC5 variants that were cited to associate this gene with X-linked ID and/or ASD include: PMID: 24817631; Mignon-Ravix, C. et al. (2014) Am. J.Med. Genet. A 164A: 1991–1997: A hemizygous 47-kb deletion in Xq23 including exon 1 of the TRPC5 gene. He had macrocephaly, delayed psychomotor development, speech delay, behavioural problems, and autistic features. Maternally inherited, and a family history compatible with X-linked inheritance (i.e., maternal great uncle was also affected, although not tested). In addition, PMID: 36323681; Leitão E. et al. (2022) cites papers with the variants p.(Pro667Thr), p.(Arg71Gln) and p.(Trp225*). NB. p.(Pro667Thr) is absent in gnomAD (v2.1.1), p.(Arg71Gln) is also absent (the alternative variant p.(Arg71Trp) is present once as heterozygous only). p.(Trp225*) is absent, and it should be noted that PTCs / LoF variants are very rare (pLI = 1). However, looking further into the three references, the evidence is not as clear or as accurate as was stated. The missense variant c.1999C>A, p.(Pro667Thr), was stated as de novo, but was actually maternally inherited but was still considered a candidate for severe intellectual disability (shown in the Appendix, Patient 93, with severe speech delay, autism spectrum disorder and Gilles de la Tourette). This patient also has a de novo MTF1 variant. Reference: PMID: 23033978; de Ligt, J. et al. (2012) N. Engl. J. Med. 367: 1921–1929). Missense variant (de novo): c.212G>A, p.(Arg71Gln), was found as part of the Deciphering Developmental Disorders (DDD) study and is shown in individual 164 in Supplementary Table 2 of PMID: 33504798; Martin, HC. et al. (2021) Nat. Commun.12: 627. Also displayed in DECIPHER (DDD research variant) with several phenotype traits, but ID and ASD are not specifically mentioned. Nonsense variant: c.674G>A. p.(Trp225*) was stated as de novo but was inherited (reference PMID: 28191890; Kosmicki, JA. et al. (2017) Nat. Genet. 49: 504–510. Supplement Table 7). This was a study of severe intellectual delay, developmental delay / autism. (NB. The de novo p.(Arg71Gln) variant from the DDD study is also listed (subject DDD 342 in Supplement 4 / Table 2).

Chern Lim gene: PGM2L1 was added gene: PGM2L1 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: PGM2L1 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: PGM2L1 were set to 33979636 Phenotypes for gene: PGM2L1 were set to severe developmental and speech delay, dysmorphic facial features, ear anomalies, high arched palate, strabismus, hypotonia, and keratosis pilaris Review for gene: PGM2L1 was set to GREEN gene: PGM2L1 was marked as current diagnostic Added comment: PMID: 33979636: - Hom/chet PTVs in 4 unrelated individuals. All four affected individuals had severe developmental and speech delay, dysmorphic facial features, ear anomalies, high arched palate, strabismus, hypotonia, and keratosis pilaris. Early obesity and seizures were present in three individuals. - Studies on patient fibroblasts and cell lines indicated that PGM2L1 deficiency causes a decrease, but not a disappearance, of the sugar bisphosphates needed for the formation of NDP-sugars and that there is no evidence that this leads to a glycosylation defect.

| Mendeliome v0.3874 | ABAT | Zornitza Stark edited their review of gene: ABAT: Added comment: Bi-allelic variants in ABAT are associated with a neurotransmitter disorder. However, there are also reports of families with encephalomyopathic MDS caused by bi-allelic variants in ABAT resulting in elevated GABA in subjects' brains as well as decreased mtDNA levels in subjects' fibroblasts. Nucleoside rescue and co-IP experiments demonstrate that ABAT functions in the mitochondrial nucleoside salvage pathway to facilitate conversion of dNDPs to dNTPs. Unclear whether this a distinct disorder or part of a continuum caused by the enzyme being part of two pathways.; Changed publications: 25738457, 27903293, 28411234, 27596361, 20052547, 10407778, 6148708; Changed phenotypes: GABA-transaminase deficiency, MIM# 613163, mtDNA depletion syndrome (MDS) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
