| Mendeliome v1.2543 | LSM1 |
Zornitza Stark edited their review of gene: LSM1: Added comment: LSM1 encodes a subunit of a complex composed of proteins LSM1-7 which is involved in mRNA stabilisation as well as degradation. Other proteins within the complex are yet to have a definitive disease association however LSM7 has been reported a candidate gene. 3 papers detail 10 affected individuals from 6 families with either a homozygous recurrent splice variant (LSM1:c.231+4A>C) or a homozygous missense variant (LSM1:p.Asn40Tyr in only 1 family). Both very rare in gnomad v4 with 0 homozygotes. The phenotype of the individuals encompassed severe intellectual disability/developmental delay, shared dysmorphic features (broad forehead, pointed chin, medially thickened arched eyebrows, hypertelorism, bulbous nasal tip), skeletal anomalies, cardiovascular (ASD/VSD/aortic valve) and genitourinary abnormalities (CAKUT/hypospadias), gastrointestinal manifestations, hypotonia and visual impairments. RT PCR of the splice variant demonstrated exon 3 skipping with a resultant truncated protein with presumed loss of function mechanism. It was noted by authors there are no biallelic loss of function variant in the gnomad v4, as such it was suggested complete loss of function is non viable. Variants outside of exon 3 have not yet been reported in affected individuals.; Changed rating: GREEN; Changed publications: 31010896, 36100156, 40204357; Changed phenotypes: Neurodevelopmental disorder, MONDO:0700092, LSM1-related |

In vitro and in vivo (zebrafish) assays supporting pathogenicity of the 2 variants. Sources: Literature |
