Genetic Variant MICALL1:p.Arg64Cys (chr22-37911995-C-T) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3

The NM_033386.4(MICALL1):c.190C>T(p.Arg64Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000155 in 1,614,076 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R64H) has been classified as Uncertain significance.

Genes affected

MICALL1 (HGNC:29804): (MICAL like 1) Enables identical protein binding activity; phosphatidic acid binding activity; and small GTPase binding activity. Involved in several processes, including plasma membrane tubulation; protein localization to endosome; and slow endocytic recycling. Located in late endosome and recycling endosome membrane. Is extrinsic component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
