Intellectual disability - microarray and sequencing v5.453 LRRC32 Achchuthan Shanmugasundram Classified gene: LRRC32 as Amber List (moderate evidence)
Intellectual disability - microarray and sequencing v5.453 LRRC32 Achchuthan Shanmugasundram Gene: lrrc32 has been classified as Amber List (Moderate Evidence).
Intellectual disability - microarray and sequencing v5.452 LRRC32 Achchuthan Shanmugasundram Publications for gene: LRRC32 were set to 30976112
Intellectual disability - microarray and sequencing v5.451 LRRC32 Achchuthan Shanmugasundram reviewed gene: LRRC32: Rating: AMBER; Mode of pathogenicity: None; Publications: 30976112, 35656379; Phenotypes: Cleft palate, proliferative retinopathy, and developmental delay, OMIM:619074; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Intellectual disability - microarray and sequencing v5.429 LRRC32 Hannah Knight reviewed gene: LRRC32: Rating: AMBER; Mode of pathogenicity: None; Publications: PMID: 35656379; Phenotypes: Cleft palate, proliferative retinopathy, and developmental delay; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Intellectual disability - microarray and sequencing v3.1116 LRRC32 Arina Puzriakova Phenotypes for gene: LRRC32 were changed from Intellectual disability; cleft palate; proliferative retinopathy to Cleft palate, proliferative retinopathy, and developmental delay, OMIM:619074
Intellectual disability - microarray and sequencing v3.773 PIGF Arina Puzriakova changed review comment from: Comment on list classification: New gene added by Zornitza Stark. Rating Red as 2 families with the same (likely founder) variant reported at present (PMID: 33386993). Phenotypes did include severe ID or DD, respectively - but additional cases with other variants in the LRRC32 gene required to substantiate causation (added founder-effect tag); to: Comment on list classification: New gene added by Zornitza Stark. Rating Red as 2 families with the same (likely founder) variant reported at present (PMID: 33386993). Phenotypes did include severe ID or DD, respectively - but additional cases with other variants in the PIGF gene required to substantiate causation (added founder-effect tag)

Intellectual disability - microarray and sequencing v3.212 LRRC32 Arina Puzriakova changed review comment from: Not associated with phenotype in OMIM or G2P.

PMID: 30976112 (2019) - homozygous stop-gain variant in LRRC32 (c.1630C>T; p.Arg544Ter) in three affected individuals from two families with global developmental delay, cleft palate, and proliferative retinopathy. In one family developmental quotient (DQ) varied from borderline low in the female (DQ = 72 at 3 years-2 months) to severely delayed in the male (DQ = 57 at 2 years-11 months). The male in the second family was even more severely delayed (DQ = 23 at 3 years-3 months).

Haplotype analysis indicates a founder effect, and therefore further cases are required to substantiate causation.; to: Not associated with phenotype in OMIM or G2P.

Intellectual disability - microarray and sequencing v3.212 LRRC32 Arina Puzriakova Tag founder-effect tag was added to gene: LRRC32.
Intellectual disability - microarray and sequencing v3.212 LRRC32 Arina Puzriakova Classified gene: LRRC32 as Red List (low evidence)
Intellectual disability - microarray and sequencing v3.212 LRRC32 Arina Puzriakova Added comment: Comment on list classification: Rated Red as there is not currently enough evidence that other variants in the LRRC32 gene are disease causing.
Intellectual disability - microarray and sequencing v3.212 LRRC32 Arina Puzriakova Gene: lrrc32 has been classified as Red List (Low Evidence).
Intellectual disability - microarray and sequencing v3.211 LRRC32 Arina Puzriakova reviewed gene: LRRC32: Rating: RED; Mode of pathogenicity: None; Publications: 30976112; Phenotypes: Global developmental delay, Speech delay, Hypotonia, Cleft palate, Proliferative retinopathy; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Intellectual disability - microarray and sequencing v3.33 LRRC32 Zornitza Stark gene: LRRC32 was added
gene: LRRC32 was added to Intellectual disability. Sources: Literature
Mode of inheritance for gene: LRRC32 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: LRRC32 were set to 30976112
Phenotypes for gene: LRRC32 were set to Intellectual disability; cleft palate; proliferative retinopathy
