Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS1

The NM_001378454.1(ALMS1):​c.3689G>A​(p.Gly1230Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000434 in 1,612,382 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/18 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. G1230G) has been classified as Likely benign.

Genes affected
ALMS1 (HGNC:428): (ALMS1 centrosome and basal body associated protein) This gene encodes a protein containing a large tandem-repeat domain as well as additional low complexity regions. The encoded protein functions in microtubule organization, particularly in the formation and maintanance of cilia. Mutations in this gene cause Alstrom syndrome. There is a pseudogene for this gene located adjacent in the same region of chromosome 2. Alternative splice variants have been described but their full length nature has not been determined.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.017245024).
BP6
Variant 2-73450216-G-A is Benign according to our data. Variant chr2-73450216-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 403935.
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000232 (35/150588) while in subpopulation AMR AF = 0.00106 (16/15108). AF 95% confidence interval is 0.000664. There are 0 homozygotes in GnomAd4. There are 19 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
